Answer:
12
Step-by-step explanation:
The formula for distance between points is
So when you inserts the coordinates in this formula, it would be
=12.08305
Usually, distance is round to whole number. So, it would be 12

Answer:
The value of the standard error for the point estimate is of 0.0392.
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 a randomly selected sample of 100 students at a University, 81 of them had access to a computer at home.
This means that
Give the value of the standard error for the point estimate.
This is s. So
The value of the standard error for the point estimate is of 0.0392.
