A certain drug is used to treat asthma. In a clinical trial of the drug, 27 of 296 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 0.05 significance level to complete parts (a) through (e) below. 1-PropZTest prop <0.09 z = 0.073116382 p= 0.5291432472 p= 0.0912162162 n = 296 ...... a. Is the test two-tailed, left-tailed, or right-tailed? O Two-tailed test O Right tailed test O Left-tailed test 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. ОА. Но: р> 0.09 О В.

I cannot figure out how to do this one, please help. Thank you
Transcribed Image Text:A certain drug is used to treat asthma. In a clinical trial of the drug, 27 of 296 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 0.05 significance level
to complete parts (a) through (e) below.
1-PropZTest
prop <0.09
z = 0.073116382
p= 0.5291432472
p= 0.0912162162
n = 296
a. Is the test two-tailed, left-tailed, or right-tailed?
O Two-tailed test
Right tailed test
O Left-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.
