Answer:
The sample size is smaller than 30, so we need to assume that the underlying population is normally distributed.
The sampling distribution of x overbar will be approximately normally distributed with mean 63 and standard deviation 5.69.
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
The sample size is smaller than 30, so we need to assume that the underlying population is normally distributed.
If it is:
The sampling distribution of x overbar will be approximately normally distributed with mean 63 and standard deviation 5.69.

Hi!
We know that a radius is a line that reaches from point A (the middle of a circle) to point B (the outer part of the circle).
Based on that information, the sentence that describes the radius the best is It is a segment from a point on the circle to the center of the circle.
Hope this helps! :)

Answer:33 unit sq.
Step by step.
As we can see it is combination of three rectangles having two same small rectangkes so area of small rectangle is 2(2×3) is 12
Bow for bigger rectangle it is (7×3) is 21
so total area is 33 sq. unit
