Question

2. There is a scientific study that claims amount of sugar consumed is related to weight gain. Another study claims amount exercise is related to weight loss. You are interested in exploring if amount of sugar consumed and amount of exercise can be used to weight loss. With the help of data below, answer following questions. sugar (grams) 50 56 58 30 52 Exercise (Hours) weight loss (pound) 13 10 16 9 12 12 15 25 20 20 35 30 36 30 34 35 35 33 14 23 12 10

Answer 1

According to the data provided, there is significant evidence that amount of sugar consumed can contribute in weight loss because p>.05 but exercise does not contribute in weight loss because p<0.05. Assuming that there is no significant difference between the two groups, the null hypotheses is accepted if p<.05 and rejected when P>0.05.The F values are provided in the table.

ANOVA
	Sum of Squares	df	Mean Square	F	Sig.
sugar	Between Groups	3196.389	7	456.627	11.275	.226
Within Groups	40.500	1	40.500
Total	3236.889	8
exercise	Between Groups	911.500	7	130.214	260.429	.048
Within Groups	.500	1	.500
Total	912.000	8

There is a high positive correlation between the exercise and weight when controlling the sugar intake variable.
