You derive S by squaring the sum of your data points, dividing by the number of total data points, and then subtracting this value from the sum of the squared data points. For example, given a set of x data points: 3, 5, 7, and 9, you would calculate the Sxx value by first squa...
Explain how to find Sxx? Calculate the p-value for H_0: mu = 78.5, H_a: mu greater than 78.5; bar x = 80.9, sigma = 14.1, n = 39. The graph of a normal curve is given. Use the graph to identify the value of \mu and \sigma. What is the value of SX+1 for the scores...
