Question
Transcribed Image Text:A sports league performs a hypothesis test at the 0,10 level of significance to determine if the proportion, p, of all times a certain referee's coin comes up heads
when flipped is different from 50%. Here are the null hypothesis Hg and the alternative hypothesis H, for the test.
Hạ p-0.5
00
Hi p+0,5
(a) The resuit of the league's hypothesis test will be to either reject or not reject the null hypothesis, H Based on whether H is in fact true or is in fact
false, fil in the table below to indicate whether the result of the test is correct, a Type i error, or a Type il error.
H, is true
H, is talse
Reject H,
(Choose one)
(Choose one)
Do not reject H. (Choose one)
(Choose one)
(b) The league takes a random sample and determines it is appropriate to use a Z test. The value of the test statistic is 1.325 (rounded to three
decimal places). Draw the appropriate figure for the test.
