Given table:
x -1 1 3 5
y -2 0 2 4
Unknown:
Slope of the line = ?
Solution:
Each x and y pair on the table lies on the line. Therefore, we can use them to find the slope;
Slope =
let us take;
x₁ = -1 x₂ = 3
y₁ = -2 y₂ = 2
Insert the parameters and solve;
Slope = =
= 1
The slope of the line is 1
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.
