Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The ages of a group of 153 randomly selected adult females have a standard deviation of 17.8 years. Assume that the
ages of female statistics students have less variation than ages of females in the general population, so let o = 17.8
years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate
the mean age of all female statistics students? Assume that we want 98% confidence that the sample mean is within
one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students
have less variation than ages of females in the general population?
The required sample size is .
(Round up to the nearest whole number as needed.)
