decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal
vas 75%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 235 high school seniors in
nis random sample, 182 believe that "getting rich" is an important goal. Can he conclude, at the 0.01 level of significance, that the
proportion has indeed changed?
Perform a two-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)
