dole pineapple inc. is concerned that the 16 ounce cans are overfilled. assume the standard deviation is .03 onces. a random sample of 50 cans has a mean weight of 16.05 ounces. at the 5% level of significance can we conclude that the mean weight is > than 16 ounces. what is the p value?

Try a onesample ztest.
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 ztest, find the pvalue by using a ztable. The pvalue 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.
