Answer:
1.282, -0.5244,...
Step-by-step explanation:
We know that Z is a standard normal variate with mean =0, and std dev =1
a) z-score separates the highest 10% from the rest of the scores
= 90th percentile = 1.282
b) z-score separates the lowest 30% from the rest of the scores
= 30th percentile = -0.5244
c) z-score separates the lowest 40% from the rest of the scores
= 40th percentile = -0.2533
d) z-score separates the lowest 20% from the rest of the score
=20th percentile = -0.8416

<em><u>Solution:</u></em>
Given that we have to find the value of "m"
Given expression is:

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>
Steps to follow:
Divide the numerator by the denominator.
Write down the whole number answer.
Then write down any remainder above the denominator.
Therefore,

Now the expression becomes,

Keep the variable "m" on L.H.S and move the constant to R.H.S

Thus value of m is equal to 3.625 or 
Answer:
Elimination
