Question
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 of 1050 adults from Country A, 1056 adults from Country B, 1117 adults from Country C, and 1026 adults from Country D. At a = 0.07, can you reject the claim that the
100-

proportion of adults in Country A who favor building new nuclear power plants in their country is the same as the proportion of adults from Country B who favor building new nuclear

power plants in their country? Assume the random samples are independent.

Identify the claim and state Ho and Ha.
The claim is "the proportion of adults in Country A who favor building new nuclear power plants in their country is
the proportion of adults from Country B who favor building new nuclear power plants in their country."
Let p, represent the population proportion for Country A and p2 represent the population proportion for Country B. State Ho and Ha.
Choose the correct answer below.
О А. Но: Р1 > P2
Ha: P1 SP2
O C. Ho: P1 < P2
Ha: P1 2 P2
B. Ho: P1 + P2
Ha: P1 = P2
O D. Ho: P1 2 P2
Hạ: P1 <P2
O E. Ho: P1 = P2
Ha: P1 # P2
O F. Ho: P1 <P2
Hại P1 > P2
Find the standardized test statistic.
Z=
