Perform a Hypothesis Test if regular excise really helps weight loss. Table below shows results for 5 people doing 30-minute exercise every day for 6 months. Does the data below suggest that the regular exercise helps weight loss? Apply significance level 0.057.

Identify the null hypothesis Ho and the alternative hypothesis HA. Create column for d-column for differences between weight before and weight after. Calculate mean (đ) and standard deviation (s) for numbers in difference column. \text { Determine the teststatistic } t=\frac{\bar{d}-0}{s / \sqrt{n}} \text { Use website }
