Answer:
the answer is option A population standard deviation
Hat is the expected number of repairs
<span>E[r] = 0.25 * 0 + 0.41 * 1 + 0.22 * 2 + 0.12* 3 </span>
<span>= 0.41 + 0.44 + 0.36 </span>
<span>= 1.21 </span>
<span>Company A is offering unlimted repairs for 25 / month = 300 / year </span>
<span>company B is offering 150 per repair * 1.21 expected number of repairs / year = expected 181.5 </span>
<span>A wants more up front and more over the course of the year for maintenance. </span>
<span>B is the better deal... But, A does give you certainty, which is worth something to some people.</span>
