Question
Chapter 8, Problem R8.8RE
a.
To determine
To explain: The effect of increase in the confidence level on the margin of error.
a.
Expert Solution
Explanation of Solution
Given:
All other things have been remained constant.
The margin of error is positively related to the confidence level which means that increase in the confidence level tends to increase the margin of error and vice versa.
Thus, it could be said that increase in the confidence level would lead increase in margin of error.
b.
To determine
To explain: The effect of quadrupling the
b.
Expert Solution
Explanation of Solution
The margin of error is negatively related to the confidence level which means that increase in the sample size tends to decrease the margin of error and vice versa.
Thus, it could be said that quadrupling the sample size would lead reduction in margin of error.
