Question

A new fitness programme is devised for people who would like to lose weight. Each participants’ weight in kg was measured before and after the fitness program to see if it is effective in reducing their weights. The following data were obtained.

Participant	#1	#2	#3	#4	#5	#6	#7	#8
Before	86	65	74	55	93	52	66	67
After	81	62	71	49	83	51	61	63

Carry out an appropriate hypothesis test to determine whether the fitness programme is effective in reducing weight. State the test hypotheses, and specify your test statistic and its distribution under the null hypothesis. Comment on your
State any assumptions you made in (i).

State an alternative hypothesis test to determine whether the fitness programme is effective in reducing weight. Justify why you did not use this hypothesis test in part (i).
