Question 36 (Mandatory) (2 points)
Psychologists conducted a study evaluating three types of learning strategies (A, B,
C) for students. The data below show how well each group of students did on a test
after using the learning strategy they were taught to use.
Strategy Strategy Strategy
A B C
8 7 9
8 5 12
8 7 8
6 5 13
What are SS group and SS_error?
a) 42; 24
Ob) 227.90; 3049.24
Oc) 13.33; 2.83
d) 41; 66

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
