NEED HELP PLEASE WITH EACH QUESTION THAT GOES ALONG WITH PICTURE, STUCK ON HOW TO COMPLETE EACH ONE..

a. Is the test​ two-tailed, left-tailed, or​ right-tailed?

b. What is the test​ statistic? 

the test statistic is  _______ ​(Round to two decimal places as​ needed.)

c. What is the​ P-value?

P-value= ______ ​(Round to three  decimal places as​ needed.)

d. What is the null​ hypothesis, and what do you conclude about​ it?
Identify the null hypothesis.
 
A. H0: p=0.05
 
B. H0: p>0.05
 
C. H0: p≠0.05
 
D. H0: p<0.05
 
Decide whether to reject the null hypothesis. Choose the correct answer below.
 
A. Reject the null hypothesis because the​ P-value is
less than or equal to the significance​ level, α.
 
B. Fail to reject the null hypothesis because the​ P-value is
greater than the significance​ level, α.
 
C. Fail to reject the null hypothesis because the​ P-value is
less than or equal to the significance​ level, α.
 
D. Reject the null hypothesis because the​ P-value is
greater than the significance​ level, α.
 
e. What is the final​ conclusion?
 
 
A.
There
is not
sufficient evidence to support the claim that
93​%
of adults own a cell phone.
 
B.
There
is
sufficient evidence to support the claim that
93%
of adults own a cell phone.
 
C.
There
is
sufficient evidence to warrant rejection of the claim that
93​%
of adults own a cell phone.
 
D.
There
is not
sufficient evidence to warrant rejection of the claim that
93​%
of adults own a cell phone.
A poll of 2,030 randomly selected adults showed that 92% of them own cell phones. The technology display below results from a test
of the claim that 93% of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and
assume a 0.05 significance level to complete parts (a) through (e).
