A production line operation is designed to fill cans with tomato sauce with a mean weight of 20 ounces. A sample of 25 cans is selected to test whether overfilling or under filling is occurring in the production line and they should stop and adjust it. Sample statistics (mean and standard deviation) are calculated. Assume the population of interest is normally distributed.
Let the p-value be 0.067 for this sample. At 0.05 level of significance, it can be concluded that the mean filling weight of the population is :
a. significantly different than 20 ounces
b. not significantly different than 20 ounces
c. significantly less than 20 ounces
d. not significantly less than 20 ounces
