A school psychologist wants to test the effectiveness of a new method of teaching . She recruits -grade students and randomly divides them into two groups. Group 1 is taught by means of the new method, while group 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the year, an achievement test (graded on a scale from 1-10) is administered and the results of the two groups are compared. Complete parts (a) through (i) below.

"is" (and any subsequent words) was ignored because we limit queries to 32 words.

you didn't show us what were a and i

Step-by-step explanation:

but if your looking for a controlled experiment and manipulated variable then the controlled experiment is the two groups and then the manipulated variable is the way the students learn

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
