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.

a. Is the test two-tailed, left-talod, or right-tailed?
◯ Two-tailed test
◯ Left-tailed test
◯ Right-tailed test
 
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. : p = 0.11
◯ B. : p 0.11
◯ C. : p > 0.11
◯ D. : p < 0.11
 
Decide whether to reject the null hypothesis. Choose the correct answer below:
◯ A. Fall to reject the null hypothesis because the P-value is greater than the significance level, .
◯ B. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, .
◯ C. Reject the null hypothesis because the P-value is less than or equal to the significance level, .
◯ D. Reject the null hypothesis because the P-value is greater than the significance level .
 
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.
