In a recent poll six hundred adults were asked a series of questions about the state of the economy and their children's future. One question was, "do you expect your children to have a better life than you have had, a worse life, or a life about the same as yours?" Suppose the responses showed 249 better, 309 worse, and 42 about the same. Use the sign test and = 0.05

to determine whether there is a difference between the number of adults who feel their children will have a better life compared to a worse life.

State the null and alternative hypotheses. (Let p = the proportion of adults who feel their children will have a better life.)

_x___H₀: p 0.50 correct

H_a: p < 0.50

H₀: p < 0.50

H_a: p = 0.50

H₀: p 0.50

H_a: p = 0.50

H₀: p = 0.50

H_a: p 0.50

H₀: p 0.50

H_a: p > 0.50

a) Find the value of the test statistic. (Round your answer to two decimal places.)

z =-0.72 correct answer

b). Find the p-value. (Round your answer to four decimal places.)
