Question

Thank you in advance 10. In linear regression between two variables, a signifcant relationship exists when the p value of the test statistic is greater than the desired level of a. True b. False 11. In hypothesis testing. Type I error is a. set at 5 percent. b smaller than or equal to 5 percent c. the probability of rejecting Ho when He is true. d. the probability of rejecting Ho when Ha is true. For a given sample size, when we increase the probability of Type I error, the probability of a Type II error 12. a. remains unchanged. b. increases c. decreases. d. is impossible to determine without more information. 13. Which of the following is NOT a valid null hypothesis? a. Ho: A120 Guidelines for the Jolly Blue Giant Health Insurance Company say that the average hospitatization for a triple hernia operation should not exceed 30 hours. A diligent auditor studied records of 16 randomly chosen triple hernia operations at Hackmore Hospital, and found a mean hospital stay of 40 hours with a standard deviation of 20 hours. "Aha! she cried, "The average stay exceeds the guideline." At " .025, the critical value for a right one-tailed) test of her hypothesis is 14. 1.753 b. 1.645 c. 2131 d. 1.960 For a right (one-tailed) test of hypothesis for a single population mean when is unknown with n 14, the value of the test statistic was 1.863. The p-value is 15 a. between 0.05 and 0.023. b. greater than 0.10 c. between 0.10 and 0.05. d. less than 0.01. 16. The critical value of the test statistic a. is calculated from the sample data b. is usually. 05 or 01 in most statistical tests c, separates the "reject" and "do not reject" regions d is determined by the test statistic

Explanation / Answer

10. P value for any test is pvalue is less than alpha.

In general, a p-value of 5% or lower is considered to be statistically significant.

Here p value is greater than alpha so not statistically significant

Hence answer is b. False
