... Critical Value For an α = 0.05 in a left-tailed test, the critical value is: –1.645 Conclusion About Null Since 0.1685 > 0.5 (or since –0.86 is not in the critical region), the conclusion is: fail to reject the null hypothesis. Final Conclusion Based on the results of the hypothesis test ...

... Example 12.6 works with two groups of data; the second group (Stat 13) has 148 students. The sample is large so the t-confidence interval would work even if the distribution of the hours of sleep were not normal. The first sample (n=25) is not large and it is necessary to check its distribution befo ...
