can You answer the following multiple question?

15. Imagine that a statistic follows the Doha distribution and we perform a test that some parameter is equal to some vgluek. Our critical values for a two-sided test at alpha level of significance are equal to LCL and RCL. We want to know whether there is evidence to conclude that the parameter is different from k. a. We have that evidence if our statistic is less than LCL or greater than RCL. b We have that evidence if the p-value is greater than alpha. c. We have that evidence if our statistic is greater than 1.96. d We have that evidence if our statistic is equal to 101119. 16. Asample of size n = 9 is drawn in which the sample mean is 5 and the population standard deviation is assumed to equal 3. The 95% confidence interval is a. 5 i 1.645 b. 5 i2.262 c. 5 i 1.833 d. 5 i 1.960I 17. To compare whether two population medians are the same, we can use which test? a. Sign test b Wilcoxon rank sum test c. Two sample t-test assuming equal variance d ANOVA 18. To compare whether more than two population medians are the same, we can use which test? e. Sign test f. ANOVA g. Two sample t-test assuming equal variance applied to each of the group pairs h. Kruskall-Wallis 19. To calculate a 95% confidence interval for the natural log of the odds ratio from a 2x2 table depicting exposure by disease, we should use a. In(OR)+ Za + 2+ +2 b. exp In(OR) + Z1- 2+ .1 + c. In(OR) +t, datb+ctd-10 + 1 + + d. exp In(OR) + t1-datb+c+d-1 + 20. The median of the t distribution with 13 degrees of freedom is equal to 0 b. Cannot be determined since we don't have the table for that distribution C. 1.645 d. -1.64512. Which is the narrowest confidence interval from a set of data? a. 95% confidence interval of the mean 90% confidence interval of the mean 99% confidence interval of the mean 53-99" 97.5% confidence interval of the mean 13. If the p-value is less than 0.05 in the test of the population parameter Ho: p = 0.5, then a. A 95% confidence interval for will definitely include 0.5. b A 95% confidence interval might contain 0.5. c. A 95% confidence interval will contain 0.3 exactly 62.43% of the time. d A 95% confidence interval contains 1.645. 14. If the p-value is less than 0.05 in a test of the population mean Ho: ,u = 0, then a. A 90% confidence interval will be wider than a 95% confidence interval. b A 95% confidence interval has probability of 95% of containing the mean parameter ,u. c. A 95% confidence interval definitely contains the population mean parameter p. d A 95% confidence interval would contain 1 about 95% of the time
