Question text The mean weight of the students at a certain college is 67.8 kg and the standard deviation is 7 kg. Assuming that the weights are normally distributed, find the probability of students that have a weight between 49.8 and 70.8 kg. Give your answer with at least 4 decimal places.

Step 1
z1 = (49.8 - 67.8) / 7 = -2.57 z2 = (70.8 - 67.8) / 7 = 0.43 Show more…
