The population of people are my family. I collected the sample based on their current height and shoe sizes. Yes my sample represents accurately the population. Please help me number 2 and 2 a, b, c, and d please. Thank you . Please show formula used to solve each problem. 2 and 2 a,b, c, and d. Thank you

1. To study about the correlation between height and shoe size, you need to collect a sample of nine (9) people using a Systematic Sampling method. a. What is the population of people? Where and how are you going to collect your sample? Does your sample accurately represent your population? Why or why not? 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 70 5 2 47 45 602 62 68 68 Shoe Size 19 3 2.5 2.0 80 76 10 10.5 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 i and s, respectively. b. Find the sample mean and sample standard deviation of the shoe sizes. Denote them as y 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. 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
