What z score in a normal distribution has 33% of all score above it?
Answer: A z score which has 33% of all scores above it, will have 67% of all scores below it.
To find the required z score, we need to find the z value corresponding to probability 0.67.
Using the standard normal table, we have:

Therefore, the z score = 0.44 has 33% of all score above it.
The surface area would be 169.37. Hope this helps!
Answer: b: s=n x 23
Step-by-step explanation:
When looking at the coordinates on the graph, each point increases by 23. 23 is multiplied by the number day it is (n)
Answer:
(D) 0.20
Step-by-step explanation:
There are 5 questions in the quiz.
Each question has 4 options to pick from
The student guesses at random for each (and every) question.
Find the probability that the student has only 1 correct answer.
- Focusing less on the "4" options and more on the "5" questions in the quiz, the probability that the student has only 1 correct answer out of 5 is
1/5 = 0.20
