The amount of syrup that people put on their pancakes is normally distributed with mean 61 mL and standard deviation 7 mL. Suppose that 45 randomly selected people are observed pouring syrup on their pancakes. Round all answers to 4 decimal places where possible.

If a single randomly selected individual is observed, find the probability that this person consumes is between 60.3 mL and 60.9 mL. =

For the group of 45 pancake eaters, find the probability that the average amount of syrup is between 60.3 mL and 60.9 mL. =

Step 1

Let *X* is the amount of people put the amount of syrup on their pancakes and it follows normal distribution with mean 61ml and standard deviation 7ml. a random sample of 45 people are observed pouring syrup on their pancakes.

Step 2

The probability that a person consumes syrup between 60.3ml and 60.9 ml is as follows:

Step 3

Using Excel formula = NORM.S.DIST (–0.0...
