+ 2 × 5
To evaluate apply the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
Parentheses
There are none for this steps so go on to the next step
Exponent:

81
so...
81 + 2 × 5
Multiplication:
81 + 2 × 5
2 × 5
10
so...
81 + 10
No division in this equation so skip this step and go to the next one
Addition:
81 + 10
91

Answer: The 95% confidence interval for the mean of x is (94.08, 101.92) .
Step-by-step explanation:
We are given that ,
A random variable x has a Normal distribution with an unknown mean and a standard deviation of 12.
i.e. 
Also, it is given that , Sample mean
having sample size : n= 36
For 95% confidence ,
Significance level : 
By using the z-value table , the two-tailed critical value for 95% Confidence interval :

We know that the confidence interval for unknown population mean
is given by :-

, where
= Sample mean
= Population standard deviation
= Critical z-value.
Substitute all the given values, then the required confidence interval will be :




Therefore, the 95% confidence interval for the mean of x is (94.08, 101.92) .
