gioup Ul 122 landomly selected adult females have a standard deviation of 18.5 years Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 18 5 years for the sample size calculalion How orapy female statistics student ages must be obtained in order to estmate the mean age of all female statistics students? Assume that we want 95% 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 thân ages of females in the general population? The required sample size is (Round up to the.nearest whole number as needed)
