In a January 2014 Quinnipiac University poll the following question was asked to a random sample of U.S. voters: €œDo you support or oppose the health care law passed by Barack Obama and Congress in 2010?€ The results from the poll are shown in the following table by age groups.

a. What proportion in each age category supports the health care law?
b. Which age category is most supportive of the health care law? Which age category is the least supportive?
c. Write out the null and alternative hypotheses for this study.
d. The table for these results can be found in the file HealthcareAge. Put that table in the Multiple Proportions applet (make sure you click on Use Table). What is the value of the MAD statistic?
e. Do at least 1,000 repetitions and fi nd a p-value.

f. Based on your p-value, how much evidence is there against the null hypothesis?
g. Comment on the ability to generalize and draw cause and- effect conclusions from these data.
