Question

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.
