Chapter 10: Q.117 (page 607)

If the p-value is 0.0062 what is the conclusion (use 伪 = 0.05)?
a. The method has no effect.
b. There is sufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years.
c. There is sufficient evidence to conclude that the method increases the proportion of HIV positive patients who develop AIDS after four years.
d. There is insufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years.

Short Answer

Expert verified

Option $(b)$ . There is sufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years.

is the answer.

Step by step solution

Given information

Given in the question that, If the p-value is $0.0062$ what is the conclusion (use $伪 = 0.05$ )?

a. The method has no effect.

b. There is sufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years.

c. There is sufficient evidence to conclude that the method increases the proportion of HIV positive patients who develop AIDS after four years.

d. There is insufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years.

Explanation

Because the p value is smaller than the level of significance in the given problem, the null hypothesis is rejected, and the proportion of HIV patients drops as a result of treatment.

$(b)$ is the answer.
