Question
Transcribed Image Text: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 246 better, 312 worse, and 42 about the same. Use the sign test and a = 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 < 0.50
H₂: P = 0.50
Ho: P ≥ 0.50
H₂: P < 0.50
O Ho: p ≤ 0.50
H₂: p > 0.50
Ho: P = 0.50
H₂: P = 0.50
Ho: P = 0.50
#
H₂: P = 0.50
Find the value of the test statistic. (Round your answer to two decimal places.)
z = 4.41
Find the p-value. (Round your answer to four decimal places.)
p-value = 0.0001

What is your conclusion?
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.
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 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.
