Answer:

(96.91, 101.09)

Step-by-step explanation:

To calculate the interval, you require the Z value at 95% confidence interval. The Z value is 1.96. The formula to calculate the confidence interval:

$X-Zs/\sqrt{x} \\X+Zs/\sqrt{x}$

Where X is the mean and s is the standard deviation and x the sample size:

$99-1.96\cdot{5}/\sqrt{22} \\99+1.96\cdot{5}/\sqrt{22}$

The interval is (96.91, 101.09)
