If the confidence level is increased from 90% to 99% for an SRS of size n, the width of the confidence interval for the mean μ will increase.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

If the confidence level is increased from 90% to 99% for an SRS of size n, the width of the confidence interval for the mean μ will:

We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.

When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.

When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.

Therefore, the correct word for our given statement is increase.
