As as a preliminary test of a new diet 10 subjects are recruited for study. Initial weights were recorded before the subjects began in 2 months, long diet following the 2 month diet, any weights were also recorded. The following results were observed.

Subject initial weight ending weight difference

1 180 170 10

2 165 160 5

3 195 205 -10

4 210 202 8

5 226 215 11

6 158 150 8

7 205 201 7

8 178 180 -2

9 183 176 7

10 174 165 9

Additionally, you have the following statistics giving to you. The average difference in weight loss (D Bar) = 5. The standard deviation of the differences in weight loss (SD) = 6.45

Set up hypotheses. In an attempt to prove that this new diet does, in fact, produce a statistically significant weight loss in 2 months.

Calculate and interpret the relevant statistics and results.
