Question: The following Table presents the mean cumulative weight loss in grams for 12 patients receiving propranolol and for 11 control patients following sweating during insulin-induced hypoglycemia.

Mean loss weight between treatment and control for 23 patients during insulin induced hypoglycemia

Note: you can assume equal variances between the two groups

In your solution write out the null and alternative hypothesis, the test statistic, critical value/p-value, and interpret your findings as follows.

a) State the null and alternative hypotheses.

b) Using a two sided alternative, do the data present sufficient evidence to conclude that the mean cumulative weight loss is different for the two groups? (Use a = 0.05)
