When we use the simple linear regression equation, we have the following results: Y = Β0 + Β1X. Y = 7836 – 502.4*X. Let’s use the data from the table and create our Scatter plot and linear regression line: Diagram 3: The above 3 diagrams are made with Meta Chart.A is the correct answer. Remember, in order to calculate the median, you must first order the values in the sample from lowest to highest. Doing so yields: 110 116 124 132 168 This sample is of size 5, and odd number, so the middle value of 124 is the sample median. 5.
