Question: Suppose we have observations on the variable weight(in pounds) for 10 people:
100, 120, 210, 175, 155, 110, 160, 185, 200, 220
a. Calculate the sample mean and sample standard deviation.
b. Suppose the scales underreport weight by 10 pounds. What is the mean and standard deviation of the correct weight in pounds?
c. What is the mean and standard deviation of weight in kilograms? Note: 1 kilogram equals 2.2046 pounds.
