Use a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: u=52,600; a = 0.01 Sample statistics: x=51,811, s= 2500, n=18 Click the icon to view the t-distribution table. What are the null and alternative hypotheses? Choose the correct answer below. OA. Ho: u252,600 Ha: u<52,600 | 0C. Ho: u<52,600...

A type I error is where we reject a true null hypothesis (Ho). a. True b. False A type II error is where we fail to reject a false null hypothesis (Ho). a. True b. False A claim may go in either in the Ho (null hypothesis) or Ha (H1, alternate hypothesis) depending on the key words in the statistical word problem. a. True b. False

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

A data set includes data from student evaluations of courses. The summary statistics are n = 84, x = 4.18, S = 0.63. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses...

Which of the following are type 1 or type 2 errors. a) You reject Ho, when H, is true. b) You do not reject, H, when H, is false. c) Null hypotheses: The average body temperature is 98.6°. Alternative hypotheses: The average body temperature is not 98.6°. You conclude not to reject that body temp average of 98.6°. when in reality it is not 98.60 d) Null hypotheses: The dropout rate for High school students is 23% Alternative hypotheses: The...
