2. You are a public health nurse working in an elementary schoolin Hamilton, Ontario. You have seen a substantial increase in thenumber of children in your school presenting with Attention DeficitDisorder (ADD). You are interested in whether a new drug developedby a local drug company improves the ability of children with ADDto maintain attention. You obtain ethics approval to study thedrug, informed consent from the parents of 24 fifth grade childrenwith ADD, administer the drug to the 24 children, and administer atest to the children to determine their ability to maintainattention while performing a task. Scores are continuous, can rangefrom 0 to 25 with higher scores reflecting a better ability tomaintain attention, and you know from previous research that scorestend to be normally distributed. Six of these students receive aplacebo containing none of the drug. Six students receive 2 mg ofthe drug, six students receive 4 mg of the drug, and six studentsreceive 6 mg of the drug. The table below summarizes the resultsfrom your study. Use these data to answer the following questions.Assume ?=0.05.

3. Placebo (0 mg)	Drug (2 mg)	Drug (4 mg)	Drug (6 mg)
   4	7	16	17
   7	8	14	18
   11	13	12	13
   11	6	11	17
   7	9	15	20
   10	9	13	15

4. a.You have one furtherprediction, and that is that children with ADD who receive the drugwill perform significantly better than children with ADD who do notreceive the drug. Conduct the appropriate test to confirm thisprediction, if the results from question a support doing thisadditional testing. Are you able to confirm your prediction?Explain, including the calculations and/or SPSS output to supportyour answer. [2 Marks]
