One study, based on responses from 1,020 randomly selected teenagers, concluded that 43% of teenagers cite grades as their greatest source of pressure. Use a 0.05 significance level to test the claim that fewer than half of all teenagers in the population feel that grades are their greatest source of pressure. Formulate the null and alternative hypotheses. Find the test statistic (z score to two decimal places), P value for the test statistic (four decimal places) and choose the correct conclusion below.
A. Do not reject H0. There is insufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure.
B. Reject H0. There is insufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure.
C. Do not reject H0. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure.
D. Reject H0. There is sufficient evidence to support the claim that fewer than half of all teenagers in the population feel that grades are the greatest source of pressure.
