Question

A simple random sample from a population with a normal distribution of 105 body temperatures has x =98.1°F and s=0.61°F. Construct a 90%

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

Answer #1

n = 105

Lower Limit =

Upper Limit =

90% Confidence interval is ( 0.3004 , 0.475 )

( 0.3004 < < 0.475
)

( 0.5481 < < 0.6892
)
