I cannot figure out how to do this one, please help. Thank you

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.
O A. Ho: p>0.09
О В. Но: р#0.09
ОС. Но: р<0.09
O D. Ho: p= 0.09
