Explanation of Solution
Given:
Population proportion ( p ) = 37%
Number of students ( n ) = 200
Number of students that agreed ( x ) = 83
Formula used:
The formula to compute the test statistic is:
Calculation:
The null and alternative hypotheses are:
The obtained output using Ti-83 plus calculator is:
Conclusion:
From the above obtained output, the p -value is 0.0937 which is below significance level of 0.05. The null hypothesis is rejected. Thus, there are insufficient evidence to agree with the claim of manager at 5% significance level.
