Let 
be the average weight of chocolate chips in each bag.
As per given , we have
Since 
is left-tailed , so we perform a left-tailed test.
Also, the population standard deviation is known 
.
So we use z-test.
Test statistic : 
Substitute given value ,
Significance level = 0.05
Decision rule : Reject 
when p-value < 0.05.
By z-table , P- value for left-tailed test = P(z<-1.96)= 1- P(z<1.96)
[∵ P(Z<-z)=1-P(Z<z)]
= 1- 0.9750
=0.025
Since , P-value(0.025) < 0.05 , so we reject the null hypothesis.
We support the claim that the machine is underfilling the bags at 0.05 significance level .
Answer:
I dont know if this is supposed to be solved a certain way for a class, but as a bargain shopper, this is what I would do to figure out the best value.
Step-by-step explanation:
First divide $10 by 4: 10.00/4=2.5 or $2.50 per card
Then, divide $14 by 6: 14.00/6=2.3333333 so about $2.33 per card
Now, just look at the two answers and see which one is less.
If you buy 4 cards for $10, you will pay $2.50 for each card and if you buy 6 cards for $14, you will pay about $2.33 for each card. Therefore, the better value would be the 6 cards for $14.

Hi there! The answer is 6.
The box including the drumsticks has a weight of 782 grams.
The box itself has a weight of 206 grams.
Therefore the drumsticks in the box have a weight of 782 - 206 = 576 grams.
Each drumstick has a weight of 96 grams.
The total amount of drumsticks have a weight of 576 grams.
Therefore there are 576 / 96 = 6 drumsticks in the box.
