Suppose the age that children learn to walk is normally distributed with mean 11 months and
standard deviation 1.5 month. 16 randomly selected people were asked what age they learned to
walk. Round all answers to 4 decimal places where possible,
Add up all the different ages that they learned to walk then divide by the total so Let’s say 1 month + 11 months + 3 months + 6 months= 21 months divided by 4 = 5.25
