Answer:
Correct option (A).
Increasing our confidence to 97% will <u>increase the margin of error</u>.
Step-by-step explanation:
The confidence interval for population mean is:

The margin of error is:

The margin of error of is directly proportional to the critical value.

So if the confidence level is increased from 95% to 97% the critical value will increase.
- The critical value of <em>z</em> for 95% confidence level is 1.96.
- The critical value of <em>z</em> for 97% confidence level is 2.17.
If the critical values increases the MOE increases.
Thus, on increasing the confidence level to 97% the margin of error will increase.
