Question

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 420 gram setting. Is there sufficient evidence at the 0.01 level that the bags are underfilled or overfilled? Assume the population is normally distributed.
State the null and alternative hypotheses for the above scenario.

Answer 1

Answer: See explanation

Explanation:

The null hypotheses for the above scenario will be the statement of no effect and it'll be the mean weight of the bag that filled will be 420 grams.

H0: μ = 420

The alternative hypotheses for the above scenario will be that the bag isn't filled with 420 grams. They are either underfilled below 420 grams or overfilled above 420 grams.

Ha: μ ≠ 420
