Using the data in BELOW find the 99% confidence interval for the variance AND standard deviation of the ages of the babies born at this particular hospital this year.____________________________________________________________________The data shown below represents the ages in months of 25 babies born at a particular hospital this year. Babies who are less than a month old are given an age of 0 months.092310011131284714766156784 Find the 95% confidence interval for the mean age of the babies born at this particular hospital this year.The mean (average) X is given calculated asX = Sum of all the ages of babies / Number of babiesX = 116/25X = 4.64 monthsStandard Deviation = SD = 3.2259The degree of freedom = d.f. = n 1 = 24The t value is t /2= t0.025 = 2.0639The 95% confidence interval is given asX +/- t /2S/n 4.64 +/- ((2.0639*3.2259)/25)
