Transcribed Image Text:A certain drug is used to treat asthma. In a clinical trial of the drug, 18 of 273 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 9% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a)
through (e) below.
1-PropZTest
prop< 0.09
z = - 1.389447351
p= 0.0823483801
p= 0.0659340659
n = 273
b. What is the test statistic?
(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.
О А. Но: р3D0.09
В. Но: р<0.09
Ос. Но: р#0.09
O D. Ho: р> 0.09
Decide whether to reject the null hypothesis. Choose the correct answer below.
O A. Fail to reject the null hypothesis because the P-value is greater than the significance level, a.
B. Reject the null hypothesis because the P-value is greater than the significance level, a.
C. Reject the null hypothesis because the P-value is less than or equal to the significance level, a.
D. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a.
e. What is the final conclusion?
A. There is not sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches.
B. There is not sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches.
