Solution for Step 1: Make X a random variable.
Using the information provided, X exhibits a normal distribution with mean and a standard deviation is .
Step 2 Next, determine the likelihood that a single randomly chosen figure will be less than 191.2.
As a result, 0.3802 percent chance exists that a single randomly chosen figure will be lower than 191.2.
Step 3
A sample size is determined from the provided data .
Consequently, the likelihood that a randomly chosen sample has a mean below 191.2
Therefore, there is a 0.0007 percent chance that a randomly chosen sample has a mean below 191.2.
