Question

Time Magazine wants to know the opinion of adult Americans to the question •"If you or your spouse were pregnant, would you want the unborn child tested for genetic defects?"

Specifically, they wanted to know what proportion of all adult Americans who would say yes to this question. They conducted a survey and selected a simple random sample of 1600 adult Americans. In the sample, 928 people answered "yes" of 1600 adult Americans. Suppose a political activist group in support of genetic testing claims that under 65% of adult Americans would want their unborn child tested for genetic defects. We conduct a test of significance at the 5% significance level to test the activist group's claim using Time Magazine's sample data.

Determine the null and alternative hypotheses.

Select one:

a. H0: p1 = p2 and HA: p1 > p2

b. H0: p = 0.65 and HA: p < 0.65

c. H0: p1 = 0.65 and HA: p2 = 0.58

d. H0: p = 0.58 and HA: p > 0.58

Determine the test statistic and p-value.

Select one:

a. z = - 5.87 and p-value = 1.0000

b. z = - 5.87 and p-value = 0.0000

c. z = -1.45 and p-value = 0.0735

d. z = 6.5 and p-value = 0.58
