QuestionSuppose 250 subjects are treated with a drug that is used to treat pain and 53 of them developed nausea. Use a 0.05 significance level to test the claim that more than 20%20 \% of users develop nausea. H1:p<0.20H_{1}: p<0.20 B. H0:p=0.20H_{0}: p=0.20 H1:p>0.20H_{1}: p>0.20 C. H0:p>0.20H_{0}: p>0.20 H1:p=0.20H_{1}: p=0.20 D. H0:p=0.20H_{0}: p=0.20 H1:p0.20H_{1}: p \neq 0.20
Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is 0.47 . (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is \square (Round to three decimal places as needed.)

Studdy Solution
Make a decision based on the P-value and significance level α=0.05 \alpha = 0.05 .
Since the P-value 0.319 0.319 is greater than α=0.05 \alpha = 0.05 , we fail to reject the null hypothesis H0 H_0 .
The P-value for this hypothesis test is:
0.319 \boxed{0.319}
