Question

Suppose a normal distribution has 50% of its area falling to the left of x=30, and 25% of its area falling to the right of x=38. The mode of the distribution is located at x= _____

What best completes the sentence?

Enter your answer as a decimal rounded to the nearest tenth, like this: 42.5

Answer 1

mode: x = 30

Explanation:

The mode of a normal distribution is the same as its mean and median. All are located such that half the area is below that value, and half is above.

__

If 50% of the area is left of x=30, the mean, median, and mode are all at x=30.
