Question 986928
<font face="Times New Roman" size="+2">


Since you didn't specify the population from which the sample was taken, nor did you provide that population's mean income and standard deviation, I get to select the population.  Given the population of families that have an income less than $80,000, the probability that 15 of them have an income higher than $90,000 is zero.
