Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears, measured in foot-pounds, is an important characteristic. A random sample of 13 gears from supplier 1 results in x1 = 281 and 51 = 14! while another random sample of 1? gears from supplier 2 results in 1'12 = 327 and 52 = 23- Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength? Use a = 0'05! and assume that both populations are normally distributed but the variances are not equal. What is {'0 for this test? to = :. Round your answer to two decimal places {e.g. 98.76)
