Answer:

The percentage decrease is 15%.

Step-by-step explanation:

To find the percent decrease of any two numbers, subtract the numbers and divide it by the original.

So in this case:

20-17÷20

= 3÷20

= 0.15

Now convert to a percent.

0.15×100 = 15%

Answer:

The t value for 99% CI for 21 df is 2.831.

The critical value that should be used in constructing the confidence interval is (64.593, 86.407).

Step-by-step explanation:

Now the sample size is less than 30 and also population standard deviation is not known.

Then we will use t distribution to find CI

t value for 99% CI for 21 df is TINV(0.01,21)=2.831

The margin of error is $E=t\times\frac{s}{\sqrt{n}}\\\\=2.831\times\frac{18.07}{\sqrt{22}}\\\\=10.907$

Hence CI is $CI=\overline{x} \pm E\\\\ =75.50 \pm 10.907\\\\=(64.593,86.407 )$
