When we take the difference between the two groups, the regression effect is adjusted and perhaps we can use the usual two-sample t-test to evaluate the treatment effect.

... otherwise you should fail to reject H0. p is larger than α, so we should fail to reject H0. That is, there is insufficient evidence in this set of data to suggest that the variances are not equal. In plain English, if p ≤ α, then assume that the variances are equal otherwise assume that the varianc ...

The factory churns out an average of 3500 cookies a day, with a standard deviation of 45. Inventory is just around the corner, and we’re expected to make above the 60th percentile. Over how ma ...

... What we have done in parts (c) and (d) is to run this random experiment 100 independent times. Thus we have taken 100 independent random samples from the distribution of X . This is called a random sample of size 100 from the distribution of X . For each of these random samples, we computed the aver ...
