Consider the following data representing the scores of two groups of students on a standardized test:
Group A: 70, 75, 80, 85, 90
Group B: 65, 70, 75, 85, 95
Calculate the following:
Using these calculations, determine the relationship between the means and standard deviations of the two groups. Let Quantity A be the difference between the means of two groups, and Quantity B be the difference between their standard deviations.
