The number of chocolate chips in an 18ounce bag of chocolate

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is normally distributed with a mean of 1176 chocolate chips and a standard deviation of 35 chocolate chips. What is the probability that a randomly selected 18-ounce bag of chocolate chip cookies contains more than 1242 chocolate chips?

z(1400) = (1400-1250)/100 = 150/100 = 3/2

P(x < 1400) = P(z < 3/2) = 0.9332
