Answer:
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 78
Standard Deviation, σ = 8.6
We are given that the distribution is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.33
Calculation the value from standard normal z table, we have,
which is the required equation.
Thus, values greater than equal to 74.22 above which 33% of the score fall.
