Let us have an example where in the random variable X is normally distributed with a mean of 40 and standard deviation of 3. Find the values of the random variable X and Z given the areas of the intervals under the standardized normal curve. 1. between 0 and Z is 0.3944 2. between 0 and Z is 0.2967 3. to the left of Z is 0.0207 4. to the right of Z is 0.0485 5. to the right of Z is 0.9292 6. to the left of Z is 0.9861
