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))
Consider the following two confidence intervals for B₁: 90% confidence interval: [0.49, 29.51] 95% confidence interval: [-2.29, 32.29] You want to test the null hypothesis that B₁ = 0 against the alternative hypothesis that ß₁ ‡ 0. Which of the following is true? Select all that apply. You reject the null hypothesis at the 5% significance level You fail to reject the null hypothesis at the 10% significance level. You fail to reject the null hypothesis at the 5% significance level You reject the null hypothesis at the 10% significance level
