5.in a lower one-tailed hypothesis test, chosen level of significance = 0.10, sample size = 55, and t-test statistic = -1.76. Which of the following is the conclusion? A) This is a high probability and the conclusion is difficult. B) The null hypothesis is rejected. C) There are many sampling errors. D) The null hypothesis cannot be rejected. 4.

You have a sample size of N = 20. You will perform a one-tailed t-test with alpha = .05. You have looked up the critical value and it is -1.73. You have calculated t-test statistics of -1.41. Which of the following is correct? Reject the null or retain the null? You have a sample size of N = 37 and you are going to perform a one-sample t-test using alpha = .05. You go to the t-table and find that...
For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.034. If the test is being conducted at 95% confidence, the null hypothesis Select one: a. is rejected. b. is not rejected. c. could be rejected or not rejected depending on the value of the mean of the sample. d. could be rejected or not rejected depending on the sample size.
Question 8 3 pts The a two-tailed hypothesis test Is related to a confidence interval at the same level of alpha. All of the answers are true. Is expressed in a probability framework with a chance of being wrong in our conclusion. Has an alternative hypothesis that uses Not Equal in the expression For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size...
