The given values are discrete. Use the continuity correction and describe the region of the normal distribution that corresponds to the indicated probability. The probability of exactly 44 green marbles
A) The area between 43.5 and 45.5
B) The area between 43.5 and 44
C) The area between 43.5 and 44.5
D) The area between 44 and 44.5

Question

Quizplus · Accepted Answer

When using the continuity correction for a discrete variable to approximate it using a continuous distribution, the probability of getting exactly 44 green marbles is represented by the area under the normal curve from 43.5 to 44.5. This accounts for the entire interval that the 44th marble could represent in a continuous distribution.
