1 answer:
Using the Central Limit Theorem, it is found that none of the samples satisfy the normal condition.
<h3>What does the Central Limit Theorem state?</h3>It states that the sampling distribution of sample means of size n has standard deviation , as long as at least one of these following conditions is respected.
- The underlying distribution is normal.
- The sample size is greater than 30.
In this problem, the underlying distributions are skewed, and both sample sizes are less than 30, hence none of the samples satisfy the normal condition.

Answer:
The height of the cone is
Step-by-step explanation:
we know that
The volume of the cone is equal to
where
B is the area of the circular base of the cone
h is the height of the cone
In this problem we have
<em>Find the area of the base B</em>
substitute the value of r
<em>Find the height of the cone</em>
assume
16 1 inches
f(x)=x²-1
g(x)=2x-3
f(x)*g(x)=(x²-1)*(2x-3)-----------> <span>this function exists for all real numbers</span>
the answer is the interval (-∞,∞)
