this question gives us a list of numbers and asks us to find the mean the numbers that it gives our 9.4, 11.3, 10.5, 7.4, 9.1, 8.4, 9.7, 5.2, 1.1 and 4.7. Now we know that our formula for the mean is explore the mean is equal to the sum of all our data points. We read that some of X I over n where n is the sample size of the number of data points that we have here. We can count em up and find that end is equal to 10. There, 10 data points You re plug all of these into a calculator will find that the some of the data points is equal to, um, 76.8. Now all that's left to do is divide the sun by the sample size will have 76 point 8/10 and we can say that that the Mean X bars go to 7.68
