Neporo4naja [7]
Answer: About 13.79% of the plants will have a height of less than 6.0 feet.
To answer this question, we first need to know how many standard deviations it is below the mean. That is called the z-score.
To find the z-score, we determine the difference of the expected value and the mean. Then, we divide that by the standard deviation.
(6 - 8.4) / 2.2 = -1.09
A height of 6 is -1.09 standard deviations below the mean. Looking up the probability for a z-score of -1.09 gives us a value of 13.79%.
