3. In the United States, the average amount of meat eaten

Dima020 [189]

If the average amount of meat eaten per person is 261 pounds per year then the average amount of meat eaten per day is 11 ounces.

Given that the average amount of meat eaten per person is 261 pounds per year.

We are required to find the average number of ounces of meat eaten per day.

There are 16 ounces in a pound. So,the average amount of meat eaten per person per year will be 261*16=4176 ounces per year.

Average number of ounces of meat eaten per day is there are 365 days in a year=4176/365=11.44 ounces per day.

Now by rounding it to the nearest ounce we will get 11 ounces.

Hence if the average amount of meat eaten per person is 261 pounds per year then the average amount of meat eaten per day is 11 ounces.

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hi

kenny6666 [7]

Using the z-distribution, we have that:

The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.

The margin of error is of 0.8 in.

The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the sum of all observations divided by the number of observations. Hence:

$\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1$

The margin of error of a z-confidence interval is given by:

$M = z\frac{\sigma}{\sqrt{n}}$

In which:

z is the critical value.
$\sigma$ is the population standard deviation.
n is the sample size.

We have to find the critical value, which is z with a p-value of $\frac{1 + \alpha}{2}$ , in which $\alpha$ is the confidence level.

In this problem, $\alpha = 0.99$ , thus, z with a p-value of $\frac{1 + 0.99}{2} = 0.995$ , which means that it is z = 2.575.

Then, the margin of error is:

$M = z\frac{\sigma}{\sqrt{n}}$

$M = 2.575\frac{1.2}{\sqrt{15}}$

$M = 0.8$

The margin of error is of 0.8 in.

The interval is:

$\overline{x} \pm M$

$\overline{x} - M = 44.1 - 0.8 = 43.3$

$\overline{x} + M = 44.1 + 0.8 = 44.9$

The interpretation is:

Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.
