To discuss: The error committed in computing the probability that a plot yielded at least 3.8 bushels and correct it.
The probability is 0.7881.
Given information:
Formula used:
The formula of the z-score is:
Calculation:
Consider, X be the random variable is
The correct probability is calculated as:
The required probability is 0.7881.
Explanation:
For the normal distribution, it is known that as per symmetry
In this case, this property is not used and the probability is computed by using:
Which is incorrect.
