1. Suppose we now want to conduct hypothesis tests to see if the population mean package weight is different than what we think it is. Use the coffee-test hilltop coffee data set as before. Now we are going to use the template provided in the data set. Lets assume that we think if the average package weight has changed it will be less than 2.99 pounds per package. This is our alternative hypothesis (Ha). Also, lets say that we would like a probability of Type I error to be alpha = .10.

Ho: Ha MU < 2.95

2. Compute a 90% confidence interval for the population proportion of females that are members of this golf club. Use the womens-golf test data set. Use the Excel template to compute this.
