Question

WonderGym is a new gym in town. They are planning some promotional programmes to draw in customers to try their programmes.

WonderGym is conducting 2 types of exercise classes (virtual and actual) for their customers.

They conducted a hypotheses test to review their revenue from last month for both types of classes (classes conducted virtually or class conducted in their premises) to see how the classes are compared.

WonderGym conducted a statistical test to determine if there is a change in these customers’ muscle mass after the one-month period.

Based on the selected scenario, discuss the statistical test conducted at 5% significance level.

You may use some or all of the following pointers to guide you:

Discuss the statistical analysis conducted
The sample size
Degree of freedom
Critical Value
The null and alternative hypotheses
One-tailed or Two-tailed test
Analysis and outcome

Scenario A-2
• Set C: Muscle mass (%) of participants at the beginning of the training sessions
• Set D: Muscle mass (%) of the participants at the end of the training sessions
