Quizplus · Accepted Answer

The expected number of breakdowns per week can be calculated by taking the total number of breakdowns over the past 30 weeks and dividing by 30.

Total breakdowns = 58
Expected breakdowns per week = 58/30 = 1.9333

Since we cannot have a fractional number of breakdowns, we round up to 2.

Therefore, the best choice is B) 2.
