Answer:
The mean amount of cereal in a box must be 23.42 ounces.
Step-by-step explanation:
Let <em>X</em> = amount of cereal in a box.
It is provided that <em>X</em> follows a normal distribution with mean <em>μ</em> and standard deviation <em>σ</em> = 0.25.
If 99% of the boxes contain 24 ounces or more of cereals then the probability statement is:
Use the <em>z</em> table to determine the <em>z-</em>value.
The value of <em>z</em> is -2.33.
Determine the value of <em>μ</em> as follows:
Thus, the mean amount of cereal in a box must be 23.42 ounces.
