Discuss a p-value approach

Discussion:

Q: The mean number of calories per 6-ounce can of tomato paste is supposed to be 150. A weight watchers group thought that was larger than 150. A random sample of 14 cans yielded a sample mean of 151.2 calories and a sample standard deviation of 2.4 calories. Do the sample results support the weight watchers' contention at the 5% significance level? Assume the distribution is approximately normal. Use the p-value approach.
