2. Use the following scenario to conduct a hypothesis test. Then use that to answer questions a-
g.
You would like to determine if the use of a new teaching intervention helps to improve attention in 5-
year-old boys. To test this hypothesis, you have separated 35 5-year-old boys into two groups, one with
the intervention (treatment group) and the other given normal class time (the control group). You
would like to test if the treatment group had longer attention times (in minutes) than the control group.
(The significance level of the test is .05)
