Question
A certain drug is used to treat asthma. In a clinical trial of the drug, 21 of 287 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. You may assume that the sample was random. Use a 0.01 significance level to complete parts (a) through (c)
below.
1-PropZTest
prop < 0.1
z = - 1.515055429
p= 0.0648791838
p= 0.0731707317
n = 287
a. What is the P-value?
P-value =
(Round to four decimal places as needed.)
b. What is the null hypothesis, and what do you conclude about it?
Identify the null hypothesis.
O A. Ho: p>0.1
O B. Ho: p= 0.1
O C. Ho: p#0.1
