A group of 9 7th grade students participated in a workshop on developing and supporting healthy romantic and platonic relationships. At the end of the workshop, they completed an evaluation that tested their knowledge. Their mean on the evaluation was a 14.5, with a standard deviation of 1.83. A group of 10 7th grade students who did not participate in the workshop also completed the evaluation. They had a mean of 3.5 and a standard deviation of 1.5. The higher the score on the evaluation the greater the knowledge on the subject. Calculate the t statistic, and determine whether it is statistically significant

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
