Problem 18E

The area covered by 1 L of a certain stain is normally distributed with mean 10$$m^{2}$$ and standard deviation 0.2$$m^{2}$$.

a. What is the probability that 1 L of stain will be enough to cover 10.3$$m^{2}$$?

b. What is the probability that 2 L of stain will be enough to cover 19.9$$m^{2}$$?

Equation transcription:

Text transcription:

m^{2}

Step-by-Step Solution:

Step 1 of 2:

(a)

In this question, we are asked to find the probability that 1 of stain will be enough to cover 10.3area.

The area covered by  of a certain stain is normally distributed with mean  and standard deviation 0.2 .

Let  be the area.

We need to find .

Here we can write,

Now we will calculate the  score because our distribution is approximately normal.

The z-score of 10.3 is z  =

From the z table, the area to the left of  is 0.9332.

therefore

Hence the probability that 1 of stain will be enough to cover 10.3area is 0.9332.

Step 2 of 2
