sume a significance level of alpha equals 0.05   and use the given information to complete parts​ (a) and​ (b) below.   Original​ claim: Less   than 57 ​% of adults would erase all of their personal information online if they could. The hypothesis test results in a​ P-value of 0.0242 . a. State a conclusion about the null hypothesis.​ (Reject Upper H 0   or fail to reject Upper H 0 ​.) Choose the correct answer below.     A. Reject   Upper H 0   because the​ P-value is greater than   alpha .   B. Reject   Upper H 0   because the​ P-value is less than or equal to   alpha .   C. Fail to reject   Upper H 0   because the​ P-value is less than or equal to   alpha .   D. Fail to reject   Upper H 0   because the​ P-value is greater than   alpha . b. Without using technical​ terms, state a final conclusion that addresses the original claim. Which of the following is the correct​ conclusion?     A. The percentage of adults that would erase all of their personal information online if they could is less   than 57 ​%.   B. The percentage of adults that would erase all of their personal information online if they could is more   than or equal to 57 ​%.   C. There is   sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is less   than 57 ​%.   D. There is not   sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is less   than 57 ​%.
