Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples 100] of 1128 adults from Country A, 1025 adults from Country B, 1041 adults from Country C, and 80- A food manufacturer claims that eating its new cereal as part of a daily diet lowers total blood cholesterol levels. The table shows 1080 adults from Country D. At a = 0.02, can you reject the claim that the proportion of adults 60- the total blood cholesterol levels (in milligrams per deciliter of blood) of seven patients before eating the cereal and after one year 35. in Country C who favor building new nuclear power plants in their country is greater than the 40- 34. of eating the cereal as part of their diets. Use technology to test the mean difference. Assume the samples are random and proportion of adults from Country D who favor building new nuclear power plants in their 20- dependent, and the population is normally distributed. At a = 0.05, can you conclude that the new cereal lowers total blood country? Assume the random samples are independent. cholesterol levels? Country A 53% Patient 2 3 5 6 Country B 51% Total Blood Cholesterol (Before) 210 220 225 245 250 260 235 Country C 47% Total Blood Cholesterol (After) 208 219 226 239 247 256 231 Country D 40% Let the blood cholesterol level before eating the cereal be population 1. Let the blood cholesterol level after eating the cereal be Identify the claim and state Ho and Ha. population 2. Identify the null and alternative hypotheses, where Ho = H1 - H2. Choose the correct answer below. The claim is "the proportion of adults in Country C who favor building new nuclear power plants in their country is O A. Ho: Hd 20 OB. Ho: Hd SO the proportion of adults from Country D who favor building new nuclear power plants in their country." HA: Hd 0 Let p, represent the population proportion for Country C and P2 represent the population proportion for Country D. State Ho and O C. Ho: Hd = 0 OD. Ho: Hd #0 Ha. HA: Hd #0 HA: Hd = 0 Choose the correct answer below. Calculate the standardized test statistic. O A. HO: P1 SP2 O B. Ho: P1 2 P2 O C. Ho: P1 > P2 Ha: P1 > P2 Ha: P1
