Essay
Perform the required hypothesis test for two population standard deviations. Assume that independent samples havebeen randomly selected from the two populations and that the variable under consideration is normally distributed onboth populations. Use the critical-value approach.
-A random sample of 16 women resulted in blood pressure levels with a standard deviation of 21.7 mm Hg. A random sample of 17 men resulted in blood pressure levels with a standard deviation of 19 mm Hg. Do the data provide sufficient evidence to conclude that there is more variation among blood pressure levels for women than among blood pressure levels for men? Use a 0.025 significance level .
