Question

Given a normal distribution with mean 50 and standard deviation 10. Find P(X>60)?
Select one:
a. 0.16
b. 0.84
c 0.74
d. Cannot be calculated​

Answer 1

Answer:

In this formula, μ is the mean of the distribution and σ is the standard deviation. The general form of the normal distribution is shown below; note the "bell-curve" shape of the graph, and note that the distribution is symmetric about the mean (peak).
