The mean undergraduate cost for tuition, room, board and fees for four-year colleges in the United States was found to be $26,489, with a standard deviation of $3204. If 36 of the four-year colleges are randomly sampled, find the probability that the mean cost for the sample schools is:

0.1787

Step-by-step explanation:

It is given that the mean cost of undergraduate program for a four year institutions for tuition, rooms fees and board was =$26,489

And the minimum  standard deviation is given as σ = $ 3204

So, the mean normal deviation is , μ = 26,489

and the standard deviation is, σ = 3204

Thus, the probability of the mean cost for sample schools is 0.1787

the solution is 12x-6y

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
