In a study conducted by the mechanical engineering department at a university, the steel rods supplied by two different companies were compared. Ten sample springs were made out of the steel rods supplied by each compa and a measure of flexibility was recorded for each. The data are provided in the accompanying table Compute both the mean and the variance in flexibility for both company A and company B. Does there appear to be a differ in flexibility between company A and company B Click the icon to view the flexiblity data The mean for company A is The mean for company Dis (Type integers or decimals. Do not round) The variance for company A is The variance for company is (Round to four decimal places as needed) Does there appear to be a difference in flexibility between company A and company B? There to be a difference in flexibility Company A's sample mean is Cim company B's sample mean, and company A's variance is company B's variance
Company A: Company B: 8.7 7.2 10.6 10.3 8.5 8.3 10.4 10.6 7.1 6.2 9.6 11.0 8.8 9.4 10.2 10.2 8.1 7.4 9.7 9.8
