Question

The part of it that is cut of says "p-value along with your decision to reject................."

A study reported that in a sample of 104 people who watch television news, 35 had elevated diastolic blood pressure levels (in millimeters of mercury, or mmHg). In a sample of 74 people who do not watch television news, 20 had elevated diastolic blood pressure levels. Can you conclude that the proportion of people with elevated diastolic blood pressure levels differs between news-watchers and those who do not watch news? Use the alpha = 0.05 level of significance. As with any hypothesis test, you must state the appropriate null and alternate hypotheses, report the value of the test statistic and the p-va your decision to reject the null hypothesis or not, and state a conclusion in the context of the problem.

Explanation / Answer

using statdisk

Alternative Hypothesis:   p1 not = p2

Pooled proportion: 0.3089888
Test Statistic, z: 0.9430
Critical z:        ±1.9600
P-Value:           0.3457

95% Confidence interval:
-0.0696933 < p1-p2 < 0.2022297

here p value greaterthan alpha

hence failed to reject null hypothesis.

accept there there is no differ in two proportions
