Question 238:A random sample of rivets from 2 suppliers were compared to see what the mean diameter was from each and a test to determine whether the population means were the same for the 2 suppliers. Now a comparison of the variation in diameter is needed. Company A has a mean of 0.375 and a standard deviation of 0.00082. Company B has a mean of 0.375 and a standard deviation of 0.03808. What is the appropriate hypothesis test to determine if the 2 suppliers have equal standard deviations (using a significance level equal to 0.05)?
