Answer 1

There could be extra weight from the bag, there could be different air pressure, it could have been weighed wrong, or there could have been something wrong with the scale. There are a lot of key factors that could have been played in this.

Answer 2

The null hypothesis (H0) in this situation is that the machine is filling the bags of pretzels correctly, and the mean weight of a bag is 8 ounces.

The alternative hypothesis (Ha) is that the machine is not filling the bags of pretzels correctly, and the mean weight of a bag is greater than 8 ounces.

Symbolically, this can be written as:

H0: μ = 8

Ha: μ > 8

where μ represents the true population mean weight of the bags of pretzels.
