Step 1

Confidence Interval:

The form of the confidence interval is,

CI = Point estimate ± Margin of error.

α is the level of significance.

The approximate 100*(1–α)% confidence interval for the population mean will be obtained using the formula given below:

Step 2

Express the confidence interval in the format that uses “less than” symbol:

Denote the population mean speed of airport data as μ.

The data represents the confidence interval for the population mean speed of airport data.

The...
