4) (4 pts) Find 99% confidence interval for the population mean of the right thumb lengths, and find the 99% confidence interval for the population mean of the right handspan.

5) (4 pts) Create a table showing the frequency and relative frequencies for each of the favorite colors.

6) (8 pts) Make a bar chart of the favorite color data. Include a title giving your name as the creator. Label the frequency axis.  Write a paragraph which includes the answers to the following questions.

7) (8 pts) At 98% confidence, test to see if the population proportion of subjects whose favorite color is blue is less than 35%.  State the test statistic, the P-value and your conclusion in English.

8) (8 pts) Run a Chi-square Goodness of Fit Test to see if the favorite colors are equally likely at 90% confidence.  State the test statistic, the P-value and your conclusion in English.

9) (10 pts) Create a scatter diagram of the right handspan versus the right thumb length with the regression line included.  Include a title giving your name as the creator.  Label each axis and include the units. Make sure horizontal and vertical grid lines are shown.

10) (2 pts) Write the equation of the regression line from the scatter plot created for problem (9) in displayed form. 

11) (8 pts) Write a paragraph (or two) that answers each of the following questions about the scatter diagram you created for problem (9).
