Type I error: A company that manufactures steel wires guarantees that the mean breaking strength (in kilonewtons) of the wires is greater than 30. They measure the strengths for a sample of wires and test Ho : p = 50 versus H : > 50. Part: 0 / 3 Part 1 of 3 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 greater than V 50. Part: 1 / 3 Part 2 of 3 If a Type II error is made, what conclusion will be drawn regarding the mean breaking strength? The conclusion will be that the mean breaking strength is less than 7 30. Part: 2 / 3 Part 3 of 3 This test uses a one-tailed 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 greater than 50. With a two-tailed hypothesis, we will not know X 5 whether the mean breaking strength is 50. less than or greater than
