Answer:
The answer here would be 0.
Step-by-step explanation:
If a and b are both equal distances from 0, then adding the together would equal 0. Since a is the inverse of b, using any number and its inverse will show you why the answer is 0. For example, if b is 9 then a would be -9. Adding these together equals 0.

The confidence interval for population mean (when population standard deviation is unknown) is given by :-

, where n= sample size
= Sample mean
s= sample size
t* = Critical value.
Given : n= 25
Degree of freedom : 

Significance level for 98% confidence interval : 
Using t-distribution table ,
Two-tailed critical value for 98% confidence interval :

⇒ The critical value that should be used in constructing the confidence interval = 2.4922
Then, the 95% confidence interval would be :-




Hence, the 98% confidence interval for the mean repair cost for the dryers. = 
Answer:
You divide what you got by how many questions there are. For example, if you got 18/20, you'd divide 18 by 20 with a calculator. Which would be 0.9, then you move the decimal over 2 times making it 90, so you got 90%
