Expert Answer

Step 1

We are given,

X: Number of pages should the manufacturer advertise for each cartridge.

Which follows normal distribution.

Step 2

Population mean = μ =12,225

SD = σ = 795

First, we have to find z-value with a left-tail of 10% as we have given right tail as 90%.

Using z-table,

z = -1.2816

Step 3
