Question

Quizplus · Accepted Answer

To calculate SX, we add all the data values: 1 + 3 + 3 + 5 = 12 To calculate SX², we first need to find the mean: (mean) = (1+3+3+5)/4 = 3 Then, we calculate the sum of squares of differences between each data value and the mean: (1-3)^2 + (3-3)^2 + (3-3)^2 + (5-3)^2 = 8 Finally, we multiply the sum of squares by 1/(n-1) where n is the sample size: 8 * 1/(4-1) = 8/3 = 2.67 Therefore, the answer is C: 12;44
