Question

In the United States, 36 percent of the people have a blood type that is A positive. From a random sample of 150 people from Norway, 66 had a blood type that was A positive. Consider a hypothesis test to investigate whether the proportion of people in Norway with a blood type of A positive is different from that in the United States. Which of the following is the standard deviation used to calculate the test statistic for the one-sample zz-test?

(0.24)(0.76)150−−−−−−−−√(0.24)(0.76)150

A
(0.44)(0.56)150−−−−−−−−√(0.44)(0.56)150

B
(0.36)(0.64)150−−−−−−−−√(0.36)(0.64)150

C
(0.44)(0.56)150√(0.44)(0.56)150

D
(0.36)(0.64)150√
