The value of z-score for a score that is three standard deviations above the mean is 3.
In this question,
A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
Let x be the score
let μ be the mean and
let σ be the standard deviations
Now, x = μ + 3σ
The formula of z-score is
⇒
⇒
⇒
Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

Given
The attached table
Required
Fill in the gaps
(a) The equation
First, we calculate the slope (m)
From the table, we can say that:
So, we have:
The equation is then calculated using:
This gives:
(b) When x = 54
Substitute 54 for x in
