Test whether the weight reducers on average will lose less than 10 pounds using P-value approach.

A new weight-watching company, Weight Reducers International, advertises that those who join would lose, on the average, 10 pounds the first two weeks with the standard deviation of 2.8 pounds. A random sample of 50 people who joined the new weight reduction program revealed the mean loss to be 9 pounds. At the .05 level of significance, can we conclude that those joining Weight Reducers on average will lose less than 10 pounds? Find the p-value.
