Answer:
The slinky situation
Step-by-step explanation:
To make a rate, divide one value by the other.
For the short bungee,
6 inches ÷ 3 pound = 2 inches per pound
While the slinky,
36 inches (remember to convert feet to inches) ÷ 1 pound = 36 inches per pound
As you can tell by the numbers, 36 inches per pound is way better than the 2 inches per pound.
Answer:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
Step-by-step explanation:
To solve this question, we use the central limit theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
In this problem, we have that:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
