This assignment is past the original due date o this data is from a sample. calculate the mean, standard deviation, and variance 16.7 11.1 46.7 14.8 13.3 16.6 18.5 47.3 42,8 show the following answers to 2 decimal places. sample mean- sample standard deviation ( use the standard deviation above for your calculation.) sample variance ooops- now you discover that the data was actually from a population! so now you must give the population standard deviation.
