Hi, I need help with the rest of the parts for this full exercise, please provide as much parts as you can. Thanks in advance. (The data is given and solved all the way to part 2D, so I need help solving part 3A,B and C). Please help and thanks in advance.

Extracted text: West Coast University Signature Assignment Page 2 of 2 3. (CLO 2) Test a claim that the mean height of your population is different from 64 inches. Use the appropriate significance level a you fixed earlier. a. State the initial and alternative hypothesis. b. Find the test statistic and the P-value. You must first write the formula for the test statistic and then substitute your appropriate numbers. c. Draw a conclusion in context of the situation. Your conclusion should include both the formal language as well as an informal explanation. 4. (CLO 3) Find a correlation between height and shoe size. a. Create a scatterplot of the data. Height is x-axis and Shoe size is y-axis. Attach your scatterplot to the end of this document. b. Find the linear correlation coefficient. What does this tell you about your data? c. Write the equation of the regression line and use it to predict the shoe size of a person that is 68 inches tall. 5. Write a paragraph or two about what you have learned from this process. When you read, see, or hear a statistic in the future, what skills will you apply to know whether you can trust the result?

(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 = O, ) 5 0.05 95% a. Find the sample mean and sample standard deviation of the height. Denote them as T and s, respectively. X= 68.556 (mean) Sx= 4.03 b. Find the sample mean and sample standard deviation of the shoe sizes. Denote them as y and sy respectively. 12. 222 (meen) Sy = 0. 971 %3D 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. .556-2.30668.556 + 2,3064.03) 65.458
