Answer:
It is not direct variation
Step-by-step explanation:
y/7 = 2/x
y = 7×2/x
y = 14/x
And
y = k/x
k = 14 which is the constant of proportionality
: y ∞ 1/x
This is inverse variation

Answer:
Will have an expected value of the mean = 80 and a standard error of the mean = 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.
In this problem, we have that:

n = 16
So the mean is 80 and the standard deviation is 
Will have an expected value of the mean = 80 and a standard error of the mean = 5
