Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

It is also represented as Point estimate ± Margin of error

Confidence level is proportional to the Margin of error.

As confidence level increases the error bound increases that makes the confidence interval broader.
As confidence level decreases the error bound decreases , making the confidence interval narrower.
