**MathGuru**, Monday, April 2, 2012 at 6:59pmTry a one-sample z-test.

Hypotheses:

Ho: µ ≤ 16 -->null hypothesis

Ha: µ > 16 -->alternate hypothesis

Data:

n = 50

sd = .03

mean = 16.05

Once you calculate z using a z-test, find the p-value by using a z-table. The p-value is the actual level of the test statistic. Compare that value to .05 to either reject the null or fail to reject the null. If you reject the null, you can conclude that the mean weight is greater than 16 ounces.

I hope this will help get you started.
