Consider the following scenario: An industrial seller of grass seeds packages its product in 50-pound bags. A customer has recently filed a complained alleging that the bags are underfilled. A production manager randomly samples a batch and measures the following weights: Weight, (lbs) 45.6 49.5 47.7 46.7 47.6 48.8 50.5 48.6 50.2 51.5 46.9 50.2 47.8 49.9 49.3 49.8 53.1 49.3 49.5 50.1 To determine whether the bags are indeed being underfilled by the machinery, the manager must conduct a test of mean with a significance level α = 0.05. In a minimum of 175 words, respond to the following: State appropriate null (Ho) and alternative (H1) hypotheses. What is the critical value if we work with a significant level α = 0.05? What is the decision rule? Calculate the test statistic. Are the bags indeed being underfilled? Should machinery be recalibrated?

Question
Consider the following scenario: An industrial seller of grass seeds packages its product in 50-pound bags. A customer has recently filed a complained alleging that the bags are underfilled. A production manager randomly samples a batch and measures the following weights:
Weight, (lbs)
45.6 49.5
47.7 46.7
47.6 48.8
50.5 48.6
50.2 51.5
46.9 50.2
47.8 49.9
49.3 49.8
53.1 49.3
49.5 50.1
To determine whether the bags are indeed being underfilled by the machinery, the manager must conduct a test of mean with a significance level α = 0.05.
In a minimum of 175 words, respond to the following:
- State appropriate null (Ho) and alternative (H1) hypotheses.
- What is the critical value if we work with a significant level α = 0.05?
- What is the decision rule?
- Calculate the test statistic.
- Are the bags indeed being underfilled?
- Should machinery be recalibrated?
