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: 41 49 53 57 a. The population mean : 53 ✓o b. The population standard debiation a: 61 56.57 49.22 49.25 47.94 48.22 57.06 52.75 51.03 45.62 48.49 65 69 a Enter an integer or decimal number (more..] Now, suppose that a random sample of size n = 10 is taken from the population above. The table below shows this sample data: Remember that you can put the data in a list and use 1-VarStats to find the sample statistics. Find (to two decimal places): a. The sample mean : 50.62✔ O 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?
