(c) The typical distance of the activity level ratings from the least-squares line is about 4.785 units. It wouldn't say it's skewed. Even though the sample size is small (3) the statistic comes from a normal distribution. C. .83 Assume that x denotes ay real number. So you can see that even though the that most of the data is concentrated on the Left and Instagram three, we do have those outliers that are at the higher values on the right side. % Okay. A rule of thumb is to use a histogram when the data set consists of 100 100 values or more. 6. Stop procrastinating with our smart planner features.
