To test this hypothesis, she randomly assigns participants to either run on a treadmill or run on an outdoor trail. She then measures their weight loss. Would it be appropriate for her to analyze her data using an independent samples t-test?

Answer:YES, It would be appropriate for her to analyze her data using an independent samples t-test

Explanation:

The independent samples t-test is used to make comparisons between two independent groups so that it can be established that there is a major difference between these two groups statistically.

It can not be used to compare more than two groups. The participants of each group will stick to their original group without interfering with the other group.

They are also assigned to each group randomly in no particular considerations.

Kimberly' s path to determining her hypothesis fit well with this test, she desires to measure the significant difference between the means of both groups and she selected and assigned them randomly
