Normal Distributions:
Finding Values A particular fruit's weights are normally distributed, with a mean of 381 grams and a standard deviation of 13 grams. The heaviest 3% of fruits weigh more than how many grams?
Give your answer to the nearest gram.
Given that,
mean =
= 381
standard deviation =
=13
Using standard normal table,
P(Z > z) = 3%
= 1 - P(Z < z) = 0.03
= P(Z < z ) = 1 - 0.03
= P(Z < z ) = 0.97
z = 1.88 (using standard normal (Z) table )
Using z-score formula
x = z *
+
x= 1.88 *13+381
x= 405.44=405
