A researcher recruited 20 participants for an experiment to determine whether there is a difference between the mean number of ideas generated per person between those who worked in a real group (group members are encouraged to share their ideas with one-another) and those who worked in a nominal group (group members are asked to not communicate with each other). Brainstorming performance is measured by the mean number of original ideas generated by group members. The task consisted of devising unusual uses for a lamp shade. Which of the following are the null and alternative hypotheses for this study (in that order and two-tailed)?
