Question:
The sample indicates that 5 out of every 300 randomly selected toys will be faulty. Consequently, a proportion can be set up that relates the unknown number of faulty toys in the total number of toys to the ratio of faulty toys to the sample: \( \frac{\mathrm{5} }{\mathrm{300}} = \frac{\mathrm{T} }{\mathrm{15000}} \)
T is the unknown number of faulty toys in the total. Multiply both sides by 15,000 and then divide the left side by 300 to solve for T: \(\frac{\mathrm{15000 \times 5} }{\mathrm{300}} = T\)
\(\frac{\mathrm{50 \times 5} }{\mathrm{1}} = T = 250\)
