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 carlier. 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 mumbers. c. Draw a conclusion in context of the situation. Your conclusion should include both the formal language as well as an informal explanation.

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 carlier.
a. State the initial and alternative bypothesis.
b. Find the test statistic and the P-value. You must first write the formula for the test statistic and then
substitute your appropriate mumbers.
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?
