What are values of the sample mean weight loss


Discussion:

Q1. Test the null hypothesis that the population mean weight loss is zero versus the alternative hypothesis that the mean weight loss is greater than zero. Use .05 and assume the population of weight loss is normally distributed. Also compute the p value.

Q2. What values of the sample mean weight loss would make you reject the null hypothesis?

Q3. Construct a 95% confidence interval for the population mean weight loss.
