Suppose that the probability of a binomial random variable X will be approximated using the normal model. Describe the area under the corresponding normal curve that will be computed for the given scenario. The probability that more than 40 individuals work from home. The area will be the area to theright left of .

The area will be the area to the right of 40.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean and standard deviation , the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the area to the left of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X, that is, the area to the right of X.

In this question:

Using the definition above, more than 40 is the area to the right of 40.

So

The area will be the area to the right of 40.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
