6. A certain drug is used to treat asthma. In a clinical trial of the drug, 25 of 256 treated subjects experienced headaches (based on data from the manufacturer). Test the claim that less than 12% 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). a. Is the test two-tailed, left-tailed or right-tailed? D A. Right tailed test O B. Left-tailed test O C. Two-tailed test b. What is the test statistic? Z = c. What is the P-value? P-value = d. What is the null hypothesis, and what do you conclude about it? DA. Ho:p = 0.12 OB. Ho:p < 0.12 O C. Ho:p + 0.12 OD. Ho:p > 0.12 Decide whether to reject to null hypothesis. Choose the correct answer below. D A. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. OB. Reject the null hypothesis because the P-value is greater than the significance level, a. O C. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. O D. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. e. What is the final conclusion? DA. There is not sufficient evidence to support the claim that less than 12% of treated subjects experienced headaches. O B. There is sufficient evidence to support the claim that less than 12% of treated subjects experienced headaches. O C. There is not sufficient evidence to warrant rejection of the claim that less than 12% of treated subjects experienced headaches. OD. There is sufficient evidence to warrant rejection of the claim that less than 12% of treated subjects experienced headaches.

Transcribed Image Text:6. A certain drug is used to treat asthma. In a clinical trial of the drug, 25 of 256 treated
subjects experienced headaches (based on data from the manufacturer). Test the
claim that less than 12% 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).
a. Is the test two-tailed, left-tailed or right-tailed?
D A. Right tailed test
O B. Left-tailed test
O C. Two-tailed test
b. What is the test statistic?
Z =
C. What is the P-value?
P-value =
d. What is the null hypothesis, and what do you conclude about it?
OA. Ho:p = 0.12
OB. Ho:p< 0.12
O C. Ho:p # 0.12
O D. Ho:p > 0.12
Decide whether to reject to null hypothesis. Choose the correct answer below.
O A. Fail to reject the null hypothesis because the P-value is less than or equal to
the significance level, a.
O B. Reject the null hypothesis because the P-value is greater than the
significance level, a.
O C. Reject the null hypothesis because the P-value is less than or equal to the
significance level, a.
O D. Fail to reject the null hypothesis because the P-value is greater than the
significance level, a.
e. What is the final conclusion?
DA. There is not sufficient evidence to support the claim that less than 12% of
treated subjects experienced headaches.
O B. There is sufficient evidence to support the claim that less than 12% of
treated subjects experienced headaches.
O C. There is not sufficient evidence to warrant rejection of the claim that less
than 12% of treated subjects experienced headaches.
OD. There is sufficient evidence to warrant rejection of the claim that less than
12% of treated subjects experienced headaches.
