The answer to your question is d
Answer:
c. normal probability distribution
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
In this question:
By the Central Limit Theorem, it is a normal distribution, so option c.
You can find this answer multiple ways.
One way is to represent it as an equation and solve for x, The total number of vehicles.
0.4x = 98
x = 245 vehicles
Or write a proportion using the fraction for 40%.
2/5 = 98/x
5 x 49 = 245
There are 245 vehicles in the garage.
Answer:
Im pretty sure ur answers would be
x= -32/27 and X= -46/27
