Answer:
Is there a proportional relationship between the number of scoops and the number of dogs?
No.
Step-by-step explanation:
A proportional relationship is something like:
y = k*x
Here y can represent the number of scoops of dog food, and x the number of dogs.
First, we know that for 4 dogs he prepares 8 scoops of dog food, then:
8 = k*4
If the relationship is proportional, then we should have a similar equation for the case of 6 dogs, where he prepares 15 scoops of dog food:
15 = k*6
So if we have the same k in both equations, then there is a proportional relationship between the number of scoops and the number of dogs.
In the first equation we have:
8 = k*4
8/4 = k
2 = k
And in the second equation we have:
15 = k*6
15/6 = k
2.5 = k
The values of k are different, so no, there isn't a proportional relationship between the number of scoops and the number of dogs.
Answer:
By the Central Limit Theorem, the mean of the average scores you get will be close to 1012.5.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean score of the population:
1012.5
If you do this many times, the mean of the average scores you get will be close to
By the Central Limit Theorem, the mean of the average scores you get will be close to 1012.5.
