Answer:
The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.
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 the population:
Mean 2 mm, standard deviation 0.04 mm
Describe the sampling distribution of X (for a sample of size 16).
Sample of size 16 means that
By the Central Limit Theorem, approximately normal with mean 2 and standard deviation
A restricted value is a value that will make the fraction undefined, and thus will make it impossible to exist.
Restricted values can exist in two forms: asymptotes and holes.
By simplifying all sides of this expression, we can find the restricted values.
After finding factors, and then cancelling like factors, keeping in mind the original factors in the denominator, we can find three restrictions:
1, 2, and -2.
