We are curious about the average number of Facebook friends that college students have. We take a simple random sample of 40 students and record the number of Facebook friends each student has. 1. The output contains a table with a lot of information. From the table, what is our sample size? What is the max value we observed? What is the minimum? What is our sample mean and sample standard deviation? 2. This table also gives you a 95% confidence interval (immediately below the mean). What is the interval? Give an interpretation of this interval.
