In a follow-up study, researchers would like to estimate the mean body temperature of healthy US adult women to within 0.05 degrees Fahrenheit, at the 88% level.

The researchers need to calculate the minimum sample size required to do this estimation. 

They will use the sample standard deviation from the previous study in place of the population standard deviation.

Find the minimum sample size required to estimate the population mean body temperature to within
0.05 degrees Fahrenheit.
Keep all of your intermediate calculations to 4 decimal places until the very end of your calculations.

The body temperatures (in degrees Fahrenheit) of a random sample of n = 50 healthy
adult women in the US was measured. The sample mean was a = 98.382 degrees
Fahrenheit and the sample standard deviation was s
0.712 degrees Fahrenheit.
