1. Collect the sample and record the data. Use a single unit for height. Do not use a mixed unit like feet and inches.

\f3. {CLD 2} Test a claim that the mean height of your population is di'erent from 64 inches. Use the appropriate signicance level o: you xed earlier. a. State the initial and alternative hypothesis. b. Find the test statistic and the P-value. You must rst 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. {CLD 3] Find a correlation between height and shoe size. a. lUreate a seatterplot of the data. Height is x-axis and Shoe size is y-axis. Attach your seatterplot to the end of this document. b. Find the linear correlation coefcient. 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 read1 see, or hear a statistic in the future... what skills will you apply to know whether you can trust the result
