TABLE 13-3 The director of cooperative education at a state college wants to examine the effect of cooperative education job experience on marketability in the work place. She takes a random sample of 4 students. For these 4, she finds out how many times each had a cooperative education job and how many job offers they received upon graduation. These data are presented in the table below. Student CoopJobs JobOffer 1 1 4 2 2 6 3 1 3 4 0 1 23. Referring to Table 13-3, set up a scatter diagram.

The t critical value she would use is ________.
TYPE: FI DIFFICULTY: Easy KEYWORDS: confidence interval, estimation of mean values, critical value
