Under name of group 2 enter: out of state students. under name of response variable enter: time. enter the below data under the heading "enter observations for each group, separated by spaces, or copy & paste from spreadsheet: " group 1: in state students: 2 4 1 2 2 2 4 7 4 1 2 2 1 group 2: out of state students: 1 2 2 3 9 1 12 5 2 2 5 1 make sure that the option "select test statistic: " says "difference of sample means". the test statistic appears at the bottom of the screen. what is the test statistic?

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

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

answer: 1, 3 and 5 are correct
