To determine whether training in a series of workshops on
creative thinking increases IQ scores, a total of 80 students are
randomly divided into treatment and control groups of 40 each.
After two months of training, the sample mean IQ (X-bar1) for the
treatment group equals 110 , and the sample mean IQ (X-bar2) for
the control group equals 108. The estimated standard error equals
1.80. Test the Null Hypothesis with t, using the .05 level of
significance and construct a 95 percent confidence interval
(whether you reject OR retain the Null Hypothesis)
