Answer:
μ= 65 inches; σ= 0.625 inch
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) 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.
In this problem, we have that:

By the central limit theorem, the sample of 16 will have:

So the correct answer is:
μ= 65 inches; σ= 0.625 inch
Answer: 
Step-by-step explanation:
By the Pythagorean theorem, the unknown side has length

Therefore,

Answer:
341..
Step-by-step explanation:
i would personally say 341 because 620 multiplied by 55% or .55, as written on a calculator, would be 341.
