Identify the two types of incorrect decisions in a hypothesis test. For each incorrect decision, what symbol is used to represent the probability of making that type of error?Choose the correct answer below.O A. A Type I error is rejecting a true null hypothesis, whose probability is denoted a.A Type Il error is not rejecting a false null hypothesis, whose probability is denoted B.O B. A Type I error is not accepting a true null hypothesis, whose probability is denoted a.A Type Il error is accepting a false null hypothesis, whose probability is denoted B.O C.

Consider a sample of 51 football games, where 26 of them were won by the home team, Use a 0,05 significance level to test the claim that the probability that the home team wins is greater than one-half. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho p=0.5 Hp0.5 Hp=0.5 OC. Ho p= 0.5 H:p 0.5 O D. Ho p=0.5 H: p>0.5
In answering a question on a multiple-choice test a student either knows the answer or guesses. Let p be the probability that she knows the answer and 1 - p the probability that she guesses. Assume that a student who guesses at the answer will be correct with probability 1/m, where m is the number of multiple-choice alternatives. What is the conditional probabil- ity that a student knew the answer to a question given that she answered it correctly?

A baseball team claims that the mean length of its games is 2.8 hours. State Ho and H, in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. O A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u= 2.8." O B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u22.8." OC. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: uS2.8." O D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.8 hours." The null hypothesis is expressed…
