Question

Suppose that you have collected a Simple Random Sample (SRS) and have calculated the following summary statistics from your data:

:	185
s:	23.75
n:	36

Use the summary statistics in the above table to calculate the Left-Hand Endpoint (LHEP) for the 95% Confidence Interval (CI) estimate of , the population variance. Round off your answer to the third decimal place, if necessary.

The LHEP of the 95% CI for  is: Blank 1. Fill in the blank, read surrounding text.

Answer 1

Therefore,

The Left Hand End Point (L.H.E.P.) of the 95% Confidence Interval (C.I.) is 370.954 (an approximate value)

Also, we assume that the sample is taken from a population that has properties similar to the Normal Distribution.
