Considering the Central Limit Theorem, we have that:
a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
b) The probability can be calculated, as the sample size is greater than 30.
<h3>What does the Central Limit Theorem state?</h3>
It states that the sampling distribution of sample means of size n is approximately normal has standard deviation
, as long as the underlying distribution is normal or the sample size is greater than 30.
In this problem, the underlying distribution is skewed right, that is, not normal, hence:
- For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
- For item b, the probability can be calculated, as the sample size is greater than 30.

22.5240 rounded to the nearest thousandth is 22.524. For this decimal
number to be rounded up rather than down, the original number would have
had to been 22.525 or higher.
Answer:
412.7 square feet
Step-by-step explanation:
A circle of circumference 72 ft will have a radius given by ...
C = 2πr
(72 ft) = 2(3.14)r
r = (72 ft)/(6.28) ≈ 11.465 ft
The area of a circle with that radius is ...
A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²
Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.
