A baseball team claims that the mean length of its games is more than 1.6 hours. State Ho and H₂ 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. OA. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 1.6 hours." The null hypothesis is expressed symbolically as, "Ho: p= 1.6." OB. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 1.6 hours." The null hypothesis is expressed symbolically as, "Ho: 21.6." OC. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 1.6 hours." The null hypothesis is expressed symbolically as, "Ho: μ‡ 1.6." D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.6 hours."

A baseball team claims that the mean length of its games is 1.6 hours. State H0 and Ha 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. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ=1.6." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.6." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.6 hours."

Do a hypothesis for the following, make sure to include and label all five steps: Test the claim that tutoring influences a student’s test scores. Use a 0.01 level of significance. Use the following before and after scores for 5 students. Before 78 79 65 78 68 After 85 83 62 85 79
Fill in the blank. The The is a value used in making a decision about the null hypothesis and is found by converting the sample statistic to a score with the assumption that the null hypothesis is true. is a value used in making a decision about the null hypothesis and is found by converting the sample statistic to a score with the assumption that the null hypothesis is true.
Describe type I and type II errors for a hypothesis test of the indicated claim. A police station publicizes that at least 60% of applicants become police officers. Describe the type I error. Choose the correct answer below. O A. A type I error will occur when the actual proportion of applicants who become police officers is at most 0.60, but you reject Ho: p≤0.60. O B. A type I error will occur when the actual proportion of applicants who become police officers is at least 0.60, but you reject Ho: p20.60. OC. A type I error will occur when the actual proportion of applicants who become police officers is at most 0.60, but you fail to reject H₁: p≤0.60. OD. A type I error will occur when the actual proportion of applicants who become police officers is at least 0.60, but you fail to reject Ho: p² 0.60. Describe the type II error.

Question 6 In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 100 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance?Enter your answer in accordance to the question statement of the tests will find significance.
If we were to run a hypothesis test, which of the following would NOT be an appropriate alternative hypothesis statement? A HA: P> 0.56 HA: > 0.99 C HAp HA p= 50 11 12 13 14 15 16 17 18 19 20
use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.
For the situation described below, state the null hypothesis, Ho, and the alternative hypothesis, H,, to be tested. (Enter != for + as needed.) A statistical test is designed to show that the mean u is different from 150. Hoi Need Help? Read It
'n each part, we have given the significance level and the P-value for a hypothesis test. For each case determine if the null hypothesis should be rejected. Write "reject" or "do not reject" (without quotations - if you like use copy and paste to avoid typos). (a) a = 0.01,P = 0.06 answer: (b) a = 0.07, P = 0.06 answer: (c) a = 0.06, P = 0.001 answer:
