Answer:
The standard error of the mean for this sample is 9.033
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:

So

The standard error of the mean for this sample is 9.033
Answer:
0
Step-by-step explanation:
if all the points lie on the same line then they have the same slope
Corresponding angles are 3 and 7, 4 and 8, and 2 and 6.
7% of 14.64 is 1.02 est.
14.64 + 1.02
= 15.66
Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to find the solutions of our given equation using u-substitution.
We can rewrite our given equation as:

Let us assume that
.






Upon substituting back the value of u, we will get:



Now we will use imaginary unit i. We know that
.


Therefore, the solutions for our given equation are
.
