For the two variables of interest: Create a scatter plot with Percent Time Asleep as the independent variable x and Longevity as the dependent variable y. The plot must include an informative title, along with correct labels for both axes. Include a plot of the least-squares equation (see #5 below). Calculate the correlation coefficient and the coefficient of determination. Identify any data points on the scatter diagram that appear to be influential. Use Cook's Distance > (4⁄√n) as the criterion...

Question 5 (25pts) Suppose the athletic director at a university would like to develop a regression model to predict the point differential for games played by the men's basketball team. A point differential is the difference between the final points scored by two competing teams. A positive differential is a win, and a negative differential is a loss. For a random sample of games,...

One measure of variation that we can look at is the Range when we have continuous variables. We will be using this measure to create a histogram. A histogram is used to show the frequencies of certain events or categories of data values in a set of data from one time period. Data are plotted in increasing or deceasing order based on the frequency count for each data categories. Assignment I Below is a data file containing the average number...
