To test Ho: p=0.45 versus H, : p

To test HO. p = 0 45 versus HI p < 0.45. a Simple random sample of n = 250 individuals is obtained and x = 105 successes are observed- If the true population proportion is 0.42 and the level of significance of 005 is used, p = 0 7576 and the power or the test is 02424, What is the and power of the test If redone at a = 001 level of significance? Poaer = (Rouhd to four deamal places as needed ) What effect does lowering the level of significance have on the power of the test? @ A. When the level of significanc* is lowered, the power of the test Increases. O B. When the level of significance is lowered, the power of the test decreases, O C. When the level of significance is lowered, the power of the test is o j O D. When the level of significance is lowered, the power of the test stays
