Question

A simple random sample from a population with a normal distribution of 106 body temperatures has x=98.50degrees Upper F and s=0.63degrees Upper F. Construct a 98% confidence interval estimate of the standard deviation of body temperature of all healthy humans. A simple random sample from a population with a normal distribution of 106 body temperatures has x = 98.50degrees Upper F and s=0.63degrees Upper F. Construct a 98% confidence interval estimate of the standard deviation of body temperature of all healthy humans.

Answer #1

A simple random sample from a population with a normal

estimate of the standard deviation of body temperature of all
healthy humans.
