Find the probability P034 z 218 using the standard normal

Find the probability P(0.34 < z < 2.18) using the standard normal distribution. Round your answer to 4 decimal places. Write your answer as a proportion (e.g. 0.1234).

Solution

From standard normal distribution for z=0.34 probability is 0.1331

For z = 2.18 probability is 0.4854

Hence the required probability is 0.6185
