Dole Pineapple Inc. is concerned that the 450 mL can of sliced pineapple is being overfilled. The population standard deviation is 0.85 mL. The quality control department took a random sample of 50 cans and found that the arithmetic mean volume was 451.4 mL. At the 5% level of significance, can we conclude that the mean volume is greater than 450 mL? Determine the p-value.
