Expert Solution
Step 1: Describing the given problem

We know that-

The confidence interval is given by

C I equals x with bar on top plus-or-minus z subscript bevelled alpha over 2 end subscript fraction numerator sigma over denominator square root of n end fraction

Here, 

x¯ = sample mean

σ = population standard deviation

n = sample size

z subscript bevelled alpha over 2 end subscript equals z minus s c o r e space c o r r e s p o n d i n g space t o space t h e space g i v e n space c o n f i d e n c e space l e v e l
