You are testing the claim that the mean GPA of night students is greater than the mean GPA of day students. You sample 20 night students, and the sample mean GPA is 2.77 with a standard deviation of 0.42 You sample 25 day students, and the sample mean GPA is 3.09 with a standard deviation of 0.64 Calculate the test statistic, rounded to 2 decimal places

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
