2. (CLO 1) Construct a confidence interval to estimate the mean height and the mean shoe size: you must complete the following questions by first choosing a Confidence Level. You may choose from the familiar 90%,95%, or 99% level of confidence. Denote this by choosing a =. a. Find the sample mean and sample standard deviation of the height. Denote them as ī and s, respectively. b. Find the sample mean and sample standard deviation of the shoe sizes. Denote them as ī and Sy respectively. c. Construct and interpret a confidence interval to estimate the mean height of the population. You must first write the formula for the confidence interval and then substitute your appropriate numbers.

Transcribed Image Text:## Sample Data Collection
**b. Collect the sample and record the data. Use a single unit for height. Do not use a mixed unit like feet and inches.**
| | Person 1 | Person 2 | Person 3 | Person 4 | Person 5 | Person 6 | Person 7 | Person 8 | Person 9 |
|-------|----------|----------|----------|----------|----------|----------|----------|----------|----------|
| Height | 72 | 69 | 64 | 69 | 71 | 74 | 70 | 67 | 61 |

**Constructing Confidence Intervals**
2. (CLO 1) Construct a confidence interval to estimate the mean height and mean shoe size. You must complete the following questions by first choosing a Confidence Level. You may choose from the familiar 90%, 95%, or 99% level of confidence.
Denote this by choosing \( \alpha = \) ________
**a.** Find the sample mean and sample standard deviation of the height. Denote them as \( \bar{x} \) and \( s_x \) respectively.
**b.** Find the sample mean and sample standard deviation of the shoe sizes. Denote them as \( \bar{y} \) and \( s_y \) respectively.
**c.** Construct and interpret a confidence interval to estimate the mean height of the population. You must first write the formula for the confidence interval and then substitute your appropriate numbers.
**d.** Construct and interpret a confidence interval to estimate the mean shoe size of the population. You must first write the formula for the confidence interval and then substitute your appropriate numbers.
