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)

8/5 is rational. It is expressed as a ratio of two integers.

√4 = 2 = 2/1 . This is rational because it expressed as ratio of two integers.

√64 = 8. This is rational because it expressed as ratio of two integers.

√10 = 3.16227..... The decimal part does not end and it is irrational because it can not be expressed as ratio of two integers.

Therefore √10 is irrational.
