The following test has been resulted before and after good diet (LFD) in order to improve the health of people. The weight of five individuals are recorded as shown below: Let μ1 be the initial weight of the individuals without LFD and μ2 be the weight a with LFD:
PERSON Weight before Weight after
1 149 142
2 194 189
3 187 184
4 196 190
5 203 199

freedom, for data collected during an experiment trying to
determine if there is at least one difference between groups. You
get a calculated F value of 7.52. Using the table below, find the
appropriate critical F value. What should be your conclusion(s),
based on those 2 F values and α?

A fitness course claims that it can improve an individual's
physical ability. To test the effect of a physical fitness course
on one's physical ability, the number of sit-ups that a person
could do in one minute, both before and after the course, was
recorded. Ten individuals are randomly selected to participate in
the course. The results are displayed in the following table. Can
it be concluded, from the data, that participation in the physical
