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.
Clown fish: angel fish 5:4
angle fish: gold fish 4:3
(60): angel fish=5:4
(5)(12)=60
(4)(12)=48 angel fish
(48): gold fish=4:3
(4)(12)=48
(3)(12)=36 gold fish
