Question 1072326: Cost of domestic airfare follows a normal distribution with a mean of $385 dollars and a standard deviation of 100. Using this information,determine what is the probability that domestic airfare will Cost $250 or less
You can put this solution on YOUR website! Cost of domestic airfare follows a normal distribution with a mean of $385 dollars and a standard deviation of 100. Using this information,determine what is the probability that domestic airfare will Cost $250 or less
z(250) = (250-385)/100 = -135/100 = -1.35
----
P(x <= 250) = P(z<= -1.35) = normalcdf(-100,-1.35) = 0.0885
