Type I error: A company that manufactures steel wires guarantees that the mean breaking strength (in kilonewtons) of the wires is greater than 50. They measure the strengths for a sample of wires and test Ho : u=50 versus H, : u>50.equal to not equal to less than If a Type II error is made, what conclusion will be drawn ro greater than trength? less than or greater than The conclusion will be that the mean breaking strength is (Choose one) 50.This test uses a onentailed alternative hypothesis. Explain why a one-tailed hypothesis is more appropriate than a two-tailed hypothesis in this situation. With a one-tailed hypothesis, we can conclude that the mean breaking strength is (Choose one) V 50. With a ' two-tailed hypothesis, we will not know whether the mean breaking strength is (Choose one) V 50. X b e If a Type I error is made, what conclusion will be drawn regarding the mean breaking strength? The conclusion will be that the mean breaking strength is (Choose one) 7 equal to not equal to less than -_ reater than less than or greater than equal to not equal to less than greater than less than or greater than
