In a fictional study, a pretest-posttest design was used to examine the influence of a television program on children's aggressiveness. The number of aggressive responses was measured during an observation period both before and after the television program.
Please refer to Table: TV and Aggressiveness in below.
(a) Determine if there is a difference in the number of aggressive behaviors in children after having viewed the television program, using a 95% confidence interval.
(b) Compute Cohen's d as a measure of effect size and interpret its meaning.

2:5, or 2/5
since we know that the larger one is 150 cubic cm,
we already know our denominator.
150/5=30, so 2x30=60 (cubic cm).
60/150=2/5 or 2:5
