Question

We have measured the time students have taken for 2 Math courses, and the time is normally distributed. We have also found that the average time is 200 days, and the standard deviation is 10. Find the probability that the time is no less than 180. Find the right expression for "the probability that the time is above 180." Find the probability that the time is above 180. a) P(Z > -2) b) P(Z ≤ -2) c) P(Z < -2)

Step 1

In this case, x = 180, μ = 200, and σ = 10. z = (180 - 200) / 10 z = -20 / 10 z = -2 Show more…
