Transcribed Image Text:A certain drug is used to treat asthma. In a clinical trial of the drug, 17 of 257 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 10% 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-PropzTest
prop <0.1
z--1.808970299
p-0.0352278089
p-0.0661478599
n-257
O B. Ho: p<0.1
O C. Ho: p>0.1
O D. Ho: p+0.1
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 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. Fail to reject the null hypothesis because the P-value is greater than the significance level, a
O D. Reject the null hypothesis because the P-value
less than
equal to the significance level, a
e. What is the final conclusion?
O A. There is sufficient evidence to support the claim that less than 10% of treated subjects experienced headaches.
O B. There is not sufficient evidence to warrant rejection of the claim that less than 10% of treated subjects experienced headaches
O C. There is sufficient evidence to warrant rejection of the claim that less than 10% of treated subjects experienced headaches.
O D. There is not sufficient evidence to support the claim that less than 10% of treated subjects experienced headaches.
