Answer:
We conclude that the machine is under filling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 436.0 gram
Sample mean,
= 429.0 grams
Sample size, n = 40
Alpha, α = 0.05
Population standard deviation, σ = 23.0 grams
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that the machine is under filling the bags.
Answer:
0.67
Step-by-step explanation:
Formula: k = y/x
k = 2/3
k = 0.66666666666
k = 4/6
k= 0.66666666666
k = 6/9
k = 0.66666666666
k = 8/12
Round 0.67
Hence, answer = 0.67
