ANSWER:
68.26%
STEP-BY-STEP EXPLANATION:
Given:
mean = 4.5 oz
standard deviation = 1 oz
x = P(3.5 < x < 5.5)
The, by empirical rule solve as,
[tex]\begin{gathered} P\mleft(3.5We calculate the values of z by means of the following table:Replacing:
[tex]\begin{gathered} P(3.5Therefore, the percentage is 68.26%
