Question

PLEASE HELP WITH THESE QUESTIONS THAT GO WITH PICTURE, NEED HELP WITH ALL PARTS

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

b. What is the test​ statistic? 

Z= _______ ​(Round to two decimal places as​ needed.)

c. What is the​ P-value?

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

d. What is the null​ hypothesis, and what do you conclude about​ it?
Identify the null hypothesis.
 
A. H0: p=0.11
 
B. H0: p>0.11
 
C. H0: p≠0.11
 
D. H0: p<0.11
 
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 warrant rejection of the claim that less than 11​% of treated subjects experienced headaches.
 
B. There is sufficient evidence to warrant rejection of the claim that less than 11% of treated subjects experienced headaches.
 
C. There is not sufficient evidence to support the claim that less than 11% of treated subjects experienced headaches.
 
D. There is sufficient evidence to support the claim that less than 11% of treated subjects experienced headaches.

 

A certain drug is used to treat asthma. In a clinical trial of the drug, 29 of 288 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 11% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.05 significance level to complete parts (a) through (e) below. 1-PropZIest prop <0.11 z = - 0.504716153 p= 0.3068791071 p= 0.1006944444 n = 288
