Answer #1

A sample mean is a point estimate of the Population mean.

Consider a sample of n=14

and the sample means =4.8936, Population S.D. is
given

Step-1: Choose a confidence level

Step-2: Find the solution c of the equation

from the table of the normal distribution.

Here the value of c is 2.326

Step-3: Compute the value of k

The limit of the Confidence interval is
