Random samples that are drawn independently from two normally distributed populations yielded the following statistics. Group 1 Group 2 n = 16 n2 = 11 x= 222.7 x,= 273.7 2 = 334.89 (The first row gives the sample sizes, the second row gives the sample means, and the third row gives the sample variances.) Can we conclude, at the 0.01 significance level, that the population variance, o, for group 1 is greater than the population variance, 0, for group 2? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
