1.Let the p-value be 0.08 for this sample. At 0.05 level of significance, it can be concluded that the mean filling weight of the population is

significantly different than 20 ounces

not significantly different than 20 ounces

significantly less than 20 ounces

not signiffcantly less than 20 ounces

2.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 underfilling is occurring in the production line and they should stop and adjust it. Sample statistics (average and standard deviation) are calculated. Assume the population of interest is normally distributed. Use this information to answer questions 22 to 23.

The p-value for this test can be calculated in Excel using the function

= 1 - NORM.S.DIST(|z-stat|, TRUE)

= 2(1 - NORM.S.DIST(|z-stat|, TRUE))

= T.DIST.RT(|t-stat|,24)

=2T.DIST.RT(|t-stat|,24)
