The average number of pounds of red meat a person consumes each year is 196 with a standard deviation of 22 pounds (Source: American Dietetic Association). If a sample of 60 individuals is randomly selected, find the probability that the mean of the sample will be Lessthan 200 pounds.

We are given,

μ = 196

σ = 22

n = 60

Step 2

We have to find probability that sample mean is less than 200 pounds.

That is,
