ears measured in foot-pounds is an important characteristic. A random sample of 10 gears from upplier 1 results in 2, = 290 and s, = 12, and another random sample of 16 gears from the econd supplier results in 8, = 321 and sz = 22. s there evidence to support the claim that supplier 2 provides gears with higher mean impact trength? Use a 0.05, and assume that both populations are normally distributed but the ariances are not equal. a. Because -4.64 < -1.714, reject the Null Hypothesis b. None among the choices c. Because -4.64 < -1.714, fail to reject the Null Hypothesis d. Reject the Null Hypothesis
