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 H0: p. : 50 versus H141 > 50. Part: 0/3 Part 1 of3 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) e-ual to not equal to less than greater than less than or reater than Are you smarter than a second-grader? A random sample of 55 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is K : 49. Assume the standard deviation of test scores is 0 :15. The nationwide average score on this test is 50. The school superintendent wants to know whether the secondgraders in her school district have weaker math skills than the nationwide average. Use the 0! : 0.01 level of significance and the Pvalue method with the TI84 calculator. Part: 0 / 4 Part 1 of4 State the appropriate null and alternate hypotheses.
