Answer:
The machine is underfilling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 435.0 grams
Sample mean, = 429.0 grams
Sample size, n = 46
Alpha, α = 0.05
Population standard deviation, σ = 24.0 grams
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Decision Rule:
If the calculated z statistic is less than the critical value of z, we fail to accept the null hypothesis and reject it.
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, the machine is underfilling the bags.
