Step 1

Given information-

Population mean,

Population standard deviation,

Sample size,

Let, X be the randomly selected value is approximately normally distributed.

Step 2

The probability that a single randomly selected value is between 221.6 and 229.1 is

(From excel using formula = NORM.S. DIST (0.170,TRUE))

(From excel using formula = NORM.S. DIST (0,TRUE))

Hence, the probability that a single randomly selected value is between 221.6 and 229.1 is 0.0675.
