The company president wishes to determine if each market segment has been penetrated equally. A sample of 100 teenagers and 200 young adults was taken for this new study. The null and alternative hypotheses were established as follows: $H_o: p = .75$ $H_a: p \neq .75$ For the teenagers using: $\bar{p} = .85$ $z = 2.31$ $p\text{-}value = .0208$ For the young adults using: $\bar{p} = .72$ $z = -.98$ $p\text{-}value = .3270$ 10. Which is the correct analysis? a. Reject $H_o$ for the teenagers and fail to reject $H_o$ for the young adults. We might expect the teenagers proportion to increase further in the future. b. Fail to reject $H_o$ for the teenagers and reject $H_o$ for the young adults. We might expect the proportion to decrease in the future. c. Reject $H_o$ for the teenagers and fail to reject $H_o$ for the young adults. We might expect the teenagers proportion to decrease in the future. d.
