The mean per capita consumption of milk per year is 140 liters with a standard deviation of 22 liters. if a sample of 233 people is randomly selected, what is the probability that the sample mean would be less than 137.01 liters? round your answer to four decimal places.

0.0192

Step-by-step explanation:

Given : The mean per capita consumption of milk per year :

Standard deviation :

Sample size :

Let be the sample mean.

The formula for z-score in a normal distribution :

For  

The P-value =

Hence, the probability that the sample mean would be less than 137.01 liters is 0.0192 .

Step-by-step explanation:

Move all terms not containing  

y

y

to the right side of the equation.
