Assume that the population distributions of times (in minutes) for two different skiers to race the same course are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics:n1=4, Xbar1= 7.52, s2=.25 n2=5, Xbar2=8.37, s2=.09 Perform the appropriate test to determine whether there is a difference in average time of skiers to race the same course
