E. In the study by Windle and Windle (1996), one of the results showed that there is a high correlation between daily cigarette consumption (no. of sticks) of mothers and daily alcohol intake (or). This means that those mothers who smoke also drink. Suppose that a parallel study is made to college seniors and the following data is obtained, would you come up with the same conclusion? Person Number of Alcohol a. Compute for the Pearson Product- Sticks Intake Day moment coefficient of conelation, r Per Day b. Find the equation of the regression line 15 1.6 between the cigarette intake and 11 1.4 alcohol intake with cigarette intake as 20 2.5 independent variable. 30 2.8 2.5 c. If a person smokes 5 sticks a day, how many ounces of alcohol does the 2.6 13 1.8 person takes in a day? 17 1.9 2.0 Evaluation A. Consider the following measurements in liters for five samples of orange juice bottled by two competing companies A and B. Compute for mean and standard deviation. I. Which company shows better bottling performance? Explain. 2. Which company is more consistent in bottling? Explain. 3. If you are to buy bottled juice, which product will you prefer? Explain. B. Compute for the mean, standard deviation and the second quartile of the data below. Interpret results. Table 1.
