A manufacturer claims that the average tensile strength of thread A exceeds the average tensile strength oi thread B by at least 11 kilograms. To test this claim. 48 pieces of each type oi thread were tested under similar conditions. Type A thread had an average tensile strength of 383 kilograms with a standard deviation of 5.01 kilograms, while type B thread had an average tensile strength of Bil? kilograms with a standard deviation of 4.67 kilograms. Test the manufacturer's claim using a 0.10 level of signicance. Do not assume that the population variances are equat. Click here to view page 1 01 the table of cn'tical values of the tdistribution.
