Ateacher claims that the proportion of students expected to pass an exam is greater than 80%. to test this claim, the teacher administers the test to 200 random students and determines that 151 students pass the exam. the following is the setup for this hypothesis test: {h0: p=0.80 ha: p> 0.80 find the test statistic for this hypothesis test for a proportion. round your answer to 2 decimal places.

provide your answer below: $$

test statistic:

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
