Answer question 3.1
![Among the 180 participating college students, 90 students were labeled as “tab
collectors" (Group 1) and 90 students were labeled as "streamlined searchers"
(Group 2). The researchers would like to use the results of this study to assess if
the population proportion of students who completed a task among "tab
collectors" (Group 1) is less than that of students labeled "streamlined searchers"
(Group 2), at a 1% significance level.
Since you are currently enrolled in a statistics course, they ask for your help in
understanding the analyses. The following table displays the observed counts of
task completion for the two groups.
