Need help with this question please.

2. Does the color of text affect reading comprehension? A group of 21 subjects, listed below, are to be divided into three groups and given identical passage to read. For Group 1, the passage will be in red, for Group 2 the passage will be in blue and for Group 3 the passage will be in black. The subjects will read the text and then be given a test for comprehension. Random divide the 21 subjects into three groups. If you use Table B, start on line 110. if you don't use Table B as suggested, write the commands you used to randomly generate numbers with whatever technology you use (calculator, Excel, etc.). (List the three groups.) Alan Beth Carl Dana Evan Fran Greg Helen Ike Jan Ken Mary Ned Opal Pete Quinn Risa Sam Tina Uma Vern Submit File
