The hypothesised value of a hypothesis test is: p=0.224. Researchers have decided that if, after sampling 488 subjects any sample proportion less than 0.196 or more than 0.252, will serve as evidence that the hypothesis is incorrect.

a) Find the absolute value of the critical values in terms of the standard normal scale, Z. Enter your answer to at least three decimal places.

b) What level of α was used here? Enter your answer to at least three decimal places. α

α=

If the actual proportion is 0.2383 what is the probability that our sample would lead us to believe the null hypothesis was incorrect? Use at least three digits.
