QUESTION 16 A 95% confidence interval of the mean is (12, 18). The result of testing Ho:u=14 against H:U#14, at 0.05 level of significance, will be O Reject the null hypothesis because 14 is more than 12 Do not reject the null hypothesis because 14 is between 12 and 18 There is insufficient information to make any conclusions about the hypothesis test O Do not reject the the null hypothesis because 14 is less than 18

true? What error we make when we fail to reject the null hypothesis when the alternative is actually A. Type I B. Type II C. No error Consider the null and alternative hypothesis: Ho: #₁ = µ2, H₂ ₁2. For which of the following 95% confidence intervals would you reject the null hypothesis? A. (-1.5, 2.5) B. (0, 2.5) C. (0.1, 2.5) Suppose you conduct a hypothesis test Ho: P₁ - P2 = 0 versus Ha: P1 P2 > 0 and obtain a test statistic z = 2.5. Which of the following is the correct Matlab command for the p-value? A. normcdf (2.5) B. 1-normcdf (2.5) C. 2*normcdf (2.5) D. 2*(1-normcdf (2.5))
We have a sample size of 36. We wish to test: Ho: m=0 H₁: m>0 -- "one sided" test Our sample: n=36. Y=8.2, s=23.9 Create a confidence interval for our null hypothesis (one sided 95% confidence interval is 1.70
