Answer:
c.My grade is 0.87 standard deviations above the mean.
Step-by-step explanation:
given that the z-score of your grade on this Statistics exam turns out to be z=0.87.
Z score is nothing but std normal variate
Any normal distribution can be converted into std normal by the transformation
Z =
Thus when z=0.87 we mean
x = Mean +0.87 sigma
Or my grade is 0.87 std deviations above the mean
Hence option C is right.
c.My grade is 0.87 standard deviations above the mean.

Hello,
Step-by-step explanation:

<u>Formula used (a+b)^2=a²+2ab+b²</u>
B cause if u add both of them alll of them they have different answer
Using it's concept, it is found that there is a 0.79 = 79% probability that he or she is content with the vacation allowance.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 500 - 105 = 395 out of 500 employees are content with the vacation allowance, hence:
p = 395/500 = 0.79.
There is a 0.79 = 79% probability that he or she is content with the vacation allowance.

So first step to solving this problem is to multiply and divide the corresponding values
3 x 100 = 300
300 + 6(10) + 8 + 4/100 + 9/1000
6 x 10 = 60
300 + 60 + 8 + 4/100 + 9/1000
4/100 = .04
300 + 60 + 8 + .04 + 9/1000
9/1000 = .009
300 + 60 + 8 + .04 + .009
now add these values together!
300 + 60 + 8 + .04 + .009 = 368.049
if you have any questions about how i solved this problem let me know:)
