b) Verify that the requirements to perform the test using the t-distribution are satisfied. Check all that apply. A. The students' test scores were independent of one another. B. The students were randomly sampled. C. The sample size is larger than 30. D. None of the requirements are satisfied. c) Use the P-value approach at the α = 0.10 level of significance to test the hypotheses in part (a). Identify the test statistic t0. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) d) Write a conclusion based on the results. Choose the correct answer below: ______ the null hypothesis and claim that there ______ sufficient evidence to conclude that the population mean is ______ than 20.

Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither. 22) Claim: μ = 981. Sample data: n = 24, x̄ = 972, s = 26. The sample data appear to come from a normally distributed population with σ = 28. A) Normal B) Neither C) Student t 23) Claim: μ = 120. Sample data: n = 11, x̄ = 100, s = 15.2. The sample data appear to come from a normally distributed population with unknown μ and σ. A) Neither B) Normal C) Student t 24) Claim: μ = 82. Sample data: n = 20, x̄ = 100, s = 15.1. The sample data appear to come from a population with a distribution that is very far from normal, and σ is unknown. A) Normal B) Student t C) Neither Provide an appropriate response. 25) If we reject the null hypothesis when the null hypothesis is true, then we have made a A) Type I error B) Correct decision C) Type α error D) Type II error

Testing Hypotheses. In Exercise, assume that a simple random sample has been selected and test the given claim. Unless specified by your instructor, use either the P-value method or the critical value method for testing hypotheses. Identify the null and alternative hypotheses, test statistic, P-value (or range of P-values), or critical value(s), and state the final conclusion that addresses the original claim. Course Evaluations Data from student course evaluations were obtained from the University of Texas at Austin. The summary statistics are n = 436, x̄ = 3.97, s = 0.55. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Do the results apply to the population of all students?
