Therefore, the 99% confidence interval for the population mean is 305 - 30 to 305 + 30, which is between 275 and 335 pages.

The correct interpretation of the 99% confidence interval is that we estimate with 99% confidence that the true population mean is between 275 and 335 pages. This is because the confidence interval is based on the sample mean and the standard deviation of the sample, and it provides a range of values within which we can be reasonably confident that the true population mean lies. The fact that the sample was randomly selected helps to ensure that the estimate is representative of the overall population of books in the library. The population standard deviation of 45 pages is used to calculate the standard error of the mean, which in turn is used to construct the confidence interval.
We estimate with 99% confidence that the true population mean is between 275 and 335 pages.

Explanation:
1. A random sample of 15 books is taken from the library.
2. The sample mean (305 pages) is calculated from the random sample.
3. The population standard deviation is given as 45 pages.
4. To construct a 99% confidence interval for the population mean, we need to use the standard deviation and the sample mean.
5. The formula for the margin of error in a confidence interval is: Margin of Error = Z-score * (Standard Deviation / \(\sqrt{SampleSize}\))
6. For a 99% confidence interval, the Z-score is approximately 2.576.
7. Margin of Error = 2.576 * (45 / √15) ≈ 30
8. The confidence interval for the population mean is: (Sample Mean - Margin of Error) to (Sample Mean + Margin of Error)
9. Therefore, the 99% confidence interval for the population mean is 305 - 30 to 305 + 30, which is between 275 and 335 pages.

the correct interpretation of the 99% confidence interval is:

"We estimate with 99% confidence that the true population mean is between 275.08 and 334.92 pages."

Based on the given information, we can calculate the 99% confidence interval for the true population mean of pages per book in the library.

Here are the steps to calculate the confidence interval:
Identify the given information:

population standard deviation \((\sigma) = 45\) pages, sample size \((n) = 15\) books, and sample mean \((\bar x) = 305\) pages.
Calculate the standard error (SE) of the sample mean:

\(SE = \sigma / \sqrt n = 45 / \sqrt 15 \approx 11.62.\)
The critical value (z) for a 99% confidence level:

\(z \approx 2.576\) (from a standard normal distribution table or using a calculator).
Calculate the margin of error (ME):

\(ME = z \times SE \approx 2.576 \times 11.62 \approx 29.92.\)
Determine the confidence interval:

\((\bar x - ME, \bar x + ME) = (305 - 29.92, 305 + 29.92) \approx (275.08, 334.92).\)

The speed at which the Moon's shadow moves across the Earth's surface near the equator during a solar eclipse is about 1,730 km/h. This can be calculated by taking the difference between the speed of the Moon's orbital motion (3,400 km/h) and the speed of the Earth's rotation at that point (1,670 km/h). the shadow moves at a speed of 1,730 km/h across the equatorial region of Earth's surface during a solar eclipse.

We need to consider the relative motion between the Moon's shadow and the Earth's surface. The Moon's shadow moves across the Earth's surface at the speed of the Moon's orbital motion, which is about 3,400 km/h. However, since the Earth is also rotating on its axis, the actual speed at which the shadow moves across a particular point on the Earth's surface is the difference between the speed of the Moon's shadow and the speed of the Earth's rotation at that point.

Near the equator, the speed of the Earth's rotation is about 1,670 km/h. Therefore, the speed at which the Moon's shadow moves across the surface of the Earth near the equator is the difference between 3,400 km/h and 1,670 km/h, which is approximately 1,730 km/h. The Moon's shadow moves from west to east at a speed of 3,400 km/h during a solar eclipse. This is the speed at which the Moon travels in its orbit. Earth rotates from west to east at a speed of 1,670 km/h near the equator. This means that, as the Moon's shadow is moving across Earth's surface, the Earth is also rotating in the same direction.

In the equation P  =  215(1.005)t/3, the value of t/3 has to be equal to 1 for a 0.5% increase.

To determine the linear function equation that best fits the data set, we need more information about the data set itself. Without the data points or any other details, we cannot accurately determine which linear function equation is the best fit.

However, I can provide a general explanation of the four options:

y = 2x + 5: This is a linear equation with a positive slope of 2. It represents a line that increases as x increases. The y-intercept is 5.

y = -1/2x + 5: This is a linear equation with a negative slope of -1/2. It represents a line that decreases at a slower rate as x increases. The y-intercept is 5.

Alessia spent $5,408 on entertainment in 2021.

To determine how much Alessia spent on entertainment in 2021, we need to work backward from the given information about her salary in 2022.

Let's assume Alessia's salary in 2021 was the same as in 2022, which is $26,000 after tax.

Since Alessia spends 35% of her after-tax salary on rent, we can calculate her rent expenditure:

Rent = 35% × $26,000

= $9,100

The remaining amount is split between food, petrol, and entertainment in the ratio 6:11:8.

To determine the ratio's total parts, we sum the individual parts:

Total parts = 6 + 11 + 8 = 25

Next, we calculate the value of one part of the ratio:

One part = ($26,000 - $9,100) / 25

= $16,900 / 25

= $676

Now, we can calculate how much Alessia spent on entertainment in 2021, which is 8 parts of the ratio:

Entertainment expenditure = 8 × $676

If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean. In repeated sampling, about 90% of the constructed confidence intervals will capture the true population mean difference. The correct answer is C.

When we construct a confidence interval, it is important to understand its interpretation. In this case, the correct answer (Oc) states that if we were to take many random samples of the same size and construct confidence intervals for each sample, approximately 90% of these intervals would contain the true population mean difference.

This interpretation is based on the concept of sampling variability. Due to random sampling, different samples from the same population will yield slightly different sample means.

The confidence interval accounts for this variability by providing a range of values within which we can reasonably expect the true population mean difference to fall a certain percentage of the time.

In the given scenario, when constructing a 90% confidence interval for the paired difference, it means that 90% of the intervals we construct from repeated samples will successfully capture the true population mean difference, while 10% of the intervals may not contain the true value.

It's important to note that this interpretation does not imply a probability or chance for an individual interval to capture the true population mean. Once the interval is constructed, it either does or does not contain the true value. The confidence level refers to the long-term behavior of the intervals when repeated sampling is considered.

Step-by-step explanation:

The probability that the sample mean is between 190 lbs and 205 lbs is approximately 0.9617.

The sample mean to lie within 2.83 lbs of the population mean with probability 68%, or in other words, we expect the sample mean to be between 197.17 lbs and 202.83 lbs with probability 68%.

The sample mean weight of 50 baby elephants is a normally distributed variable with a mean of 200 lbs and a standard deviation of \(20/\sqrt{(50)} lbs = 2.83 lbs\)(by the central limit theorem).

The standard normal distribution to calculate the probability that the sample mean is between 190 lbs and 205 lbs:

z1 = (190 - 200) / 2.83 = -3.53

\(z2 = (205 - 200) / 2.83 = 1.77\)

\(P(-3.53 < Z < 1.77) = P(Z < 1.77) - P(Z < -3.53)\)

= 0.9619 - 0.0002

= 0.9617

The interval within which we expect the sample mean to lie within probability 68%, we need to find the values of x that satisfy the following equation:

\(P(\mu - x < X < \mu + x) = 0.68\)

X is the sample mean weight and \(\mu = 200\) lbs.

Using the formula for the standard error of the mean, we can rewrite this equation as:

\(P(-x / (20 / \sqrt{(50)}) < Z < x / (20 / \sqrt{(50)})) = 0.68\)

Z is a standard normal variable.

From the standard normal distribution table, we find that the 68% probability interval is from -1 to 1.

Therefore, we can solve for x as follows:

\(x / (20 / \sqrt{(50)}) = 1\)

\(x = 20 / \sqrt{(50)}\)

\(x \approx 2.83\)
