Transcribed Image Text:You may need to use the appropriate appendix table or technology to answer this question.
In a recent poll 600 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 244 better, 314 worse, and 42 about the same. Use the sign test and α = 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.)
Ho: p =

What is your conclusion?
Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the number of adults
who feel their children will have a better life compared to a worse life.
Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the number of
adults who feel their children will have a better life compared to a worse life.
