A researcher records the amount of time (in minutes) that parent child pairs spend on social networking sites to test whether they show any generational differences. From the following findings in APA format, interpret these results by stating the research design used (repeated measures or matched pairs), the sample size, the decision, and the effect size.
Parents spend significantly less time on social networking sites compared their children (MD = -42 minutes), t(29) = 4.021, p < .05, d = 0.49.
(a) What research design was used? (Repeated measures or matched paires?)
(b) What is the sample size? (n = ?)
(c) What is the decision? (Retain or reject the null?)
(d) Based on the estimated Cohen's d, d = 0.49, what is the effect size? (Medium, Large, Small, or Trivial?)

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
