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.

Hi Bartleby Team, I need help with the last part of this exercise, part 1, 2 and 3 are done but I need help with the part 4(CLO 3) A,B,C please. Thanks in advance.
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. Ho:p= 64 Ha:p#64 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. t= 68.556-64 4.03 3. 3916 ニ Vn c. Draw a conclusion in context of the situation. Your conclusion should include both the formal language as well as an informal explanation. iguificance leve (= 5% a=0.05 e Keject the nul hypthesis, there are to conclude thot the mean height of populotion significantly differs from 64 inches. sufficient evridence 4.
