The dataset includes information about their weight before starting, weight 6 weeks later and which plan was followed, as well as some demographic information

a. Did people lose weight, regardless of what plan? Visualize the data appropriately and conduct an appropriate test.

b. Was one plan more effective than the other? Visualize the data appropriately and conduct an appropriate test.

c. Write a methods sentence that describes your analyses, citing R as discussed.d. Write a results sentence that clearly reports your findings, for each of the tests you conducted.
