Given Information:
Mean = μ = 74
Standard deviation = σ = 8
Mary's score = x = 80
Bob’s score = z = +1.50
Sue’s score = above the mean by 10 points
Required Information:
If the students are placed in order from smallest score to largest score, what is the correct order?
Answer:
Mary = 80, Sue = 84, Bob = 86
Explanation:
Bob's score:
z = (x - μ)/σ
x - μ = zσ
x = zσ + μ
x = 1.50*8 + 74
x = 12 + 74
x = 86
Sue's score:
x = u + 10
x = 74 + 10
x = 84
Mary's score:
x = 80
From the smallest score to largest score
Mary = 80, Sue = 84, Bob = 86
Because he's been on the range for such a long time.
Answer:
the representative heuristic.
Explanation:
While confronted with confusion people often attempt to make a decision, by relying on a mental shortcut described as heuristic representatives. Heuristics are used we make quick decisions using past experiences. While these shortcuts may accelerate the process of decision making, it may also result in faulty choices and stereotypes. As per the question, Piper used heuristic to quickly judges the person.
