In Statistics, it is very important for you to be able to distinguish between sample statistics and population parameters. Suppose that the graph below describes a population. 37 Find: 44 51 58 65 72 a. The population mean : b. The population standard deviation o: 79 86 69.63 86.94 66.01 72.19 56.72 72.05 71.76 54.98 62.76 58.75 93 Now, suppose that a random sample of size n = 10 is taken from the population above. The table below. shows this sample data: c. The sample mean : o Remember that you can put the data in a list and use 1-VarStats to find the sample statistics. Find (to two decimal places): d. The sample standard deviation s: Now, let's imagine that the data in this question represents the ages of people. e. If you took a census of all people in the population, what would be the average age? f. What was the average age of the ten people that were sampled?
