2. A researcher wishes to determine if there is a relationship between hospital food and patients' hunger. He measures hunger in amount of saliva secreted in one minute. First, he gathers data on eight patients' saliva secretion when they do not have hospital food. Next, he places hospital food on those same eight patients' bed trays and measures their salvia secretion (data in table below).At = .01, can he statistically prove that hospital food alters saliva secretion and therefore hunger?

Pt	No Hospital Food Present (Oz per minute)	Hospital Food Present (Oz per minute)
1	0.37	0.52
2	0.34	0.35
3	0.39	0.46
4	0.38	0.35
5	0.36	0.46
6	0.24	0.6
7	0.23	0.52
8	0.2	0.57

Step 1: In terms of the problem, state the Null and Alternative Hypothesis (2 pts)

Step 2: "Look Up" the critical value (Decide if this is a one or two tailed test).(2 pts)

Step 3: Compute the t test value based on the data. (You must determine if this scenario requires an independent or a dependent t-test).(5 pts)

Step 4: Decide to accept or reject the Null Hypothesis (2 pts)

Step 5: Summarize the results in terms of the problem. (2 pts)
