A serious side effect of allergy medicines is that they cause drowsiness, which can cause many problems for the individuals taking them.In recent years, a new non-drowsy allergy medicine has been developed.The company that created the medicine claims to be the first, once-a-day, non-drowsy allergy medicine (call it Medicine A).An independent research group wanted to check on this claim by comparing Medicine A with another allergy medicine not advertised as non-drowsy (call it Medicine B).A random sample of 3,193 allergy sufferers was selected and each individual was randomly assigned to take either Medicine A or Medicine B.From the Medicine A group, 114 of 1,604 reported drowsiness and from the Medicine B group, 155 of 1,589 reported drowsiness.

• Calculate and label the two sample proportions separately.Next, calculate the difference between these sample proportions by subtracting (Medicine A - Medicine B). Label each of them and round each of these values to four decimal places.
