.Researchers are testing the breaking strength of a new brand of rope using a large sample of ropes. In a test of Ho: p=0.80 versus Ha: p>0.80, where p is the true proportion of all ropes of this brand that would break when subjected to a weight of 1000 pounds, the test statistic is z = 1.45. Which of the following is true? (A) Ho is rejected at the 5% level, but not at the 10% level of significance. (B) Ho is rejected at the 10% level, but not at the 5% level of significance. (C) Ho is rejected at both the 5% and 10% level of significance. (D) Ho is not rejected at both the 5% and 10% level of significance. (E) Ho is not rejected at any level of significance.
