Due to the higher z-score, the correct option regarding the highest relative score is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
<h3>What is the z-score formula?</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
The z-score measures how many standard deviations the measure is above or below the mean, hence the higher the z-score, the higher the score X is relative to other scores.
The respective z-scores for this problem are given by:
- (1136 - 1080)/67.8 = 0.83.
- (4730 - 3960)/555.5 = 1.39.
Hence the correct option is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.

Answer:
A=25
Step-by-step explanation:
Answer:
One solution
Step-by-step explanation:
Expanding the equation, we get
-2w-12-6w=4w+12
Subtracting 4w from both sides, we get
-12w-12=12
Now adding 12 to both sides,
-12w=24
Solving for w, we get
w=-2
So there is only one solution to the equation.
Answer:
a) Continuous
b) Continuous
c) Discrete
d) Continuous
e) Discrete
Step-by-step explanation:
Discrete variable
Discrete variables are numerical variables that have a countable number of values between any two values. A discrete variable is always numerical. For example, the number of people with blood type Upper A in a random sample of 42 people.
Continuous variable
Continuous variables are numerical variables that have an infinite number of values between any two values. A continuous variable can be numeric or date / time. For example, the time it takes to fly from City Upper A to City Upper B.
