WebStatistics and Probability questions and answers Multiple Choice: In testing the hypotheses H0: B1 = 0 vs. Ha: B1 ≠ 0 with alpha = 0.05, the calculated value of our test statistic is T = 3.45. The critical value from our t-table is t0.025 = 2.306. What conclusion should be made? Web1) We calculate how probable it is that we would have seen the observed data if H0 is true. 2) We then either reject H0 (or fail to reject it) depending on how often we are willing to …
When Do You Reject the Null Hypothesis? (3 Examples)
WebThe null hypothesis (H0) is a statement of no difference, no association, or no treatment effect. The alternative hypothesis, Ha is a statement of difference, association, or … Weba. Using a significance level of α=0.05 , find the critical value (s). b. Should we reject H0 or should we fail to reject H0 ? arrow_forward. In a test of H0: µ=150 against HA: µ<150, a sample of size 250 produces Z = -0.65 for the value of the test statistic. Thus the p-value is approximately equal to. the very reverend canon
