To lest Hop 0.45 versus H, p<0.45, a simple random sample of n-450 individuals is obtained and x 189 successes are observed. If the true population proportion is 0.42 and the level of
significance of a 0.05 is used, p-06440 and the power of the test is 0.3500
What is the and power of the test if redone at a 0.01 level of significance?
pu
Power
(Round to four decimal places as needed)
What effect does lowering the level of significance have on the power of the test?
OA. When the level of significance is lowered, the power of the test decreases
OB. When the level of significance is lowered, the power of the test increases
OC. When the level of significance is lowered, the power of the test stays constant
OD. When the level of significance is lowered, the power of the test is 0.
