Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Given that:
M = 27, sample of n = 36 scores, µ = 30 and σ = 18.
The z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. If the z score is positive, the raw score is greater than the mean and if the z score is negative the raw score is less than the mean. The z score is given as:

Given that M = 27, this means that x = 27. Therefore:

This sample mean corresponds to a z-score of z = –1.00.
Answer:
the answers are B,D and E
Step-by-step explanation:
Answer:
I think 3/4 will be the answer if you let
(-5 2) =(x1 y1)
(3 8) =( x2 y2)
y1-y2/x2-x2
8-2/3+5
6/8
3/4
