Question 986928: in a random sample of 35 families what is the possibility that more than 15 families have income higher than 90 thousand dollars? Answer by solver91311(24713) (Show Source):
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.
