9.2 Normal Probability Distribution
Lab 9.2.1
In a standard normal distribution, where the mean is zero and standard deviation is one, what is the probability of obtaining a value (z-value) less than 1.5?
Lab 9.2.2
The average college cost per year is $27191 with the standard deviation of $7126. Assume the distribution is normal.
- Find the probability that a randomly selected college will cost less than
$27726per year.
Inverse Normal
Lab 9.2.3
The average college cost per year is $27,191 with standard deviation of $7,126. Assume the distribution is normal.
- Find the 75th percentile for this distribution
