It tests whether people with permanent contracts [group 2; n=75] evaluate their supervisor differently than people with a temporary contract ______. It calculates the 95% confidence interval of the difference in averages, µ1 - µ2. This interval turns out to be µ[-0.04; 0.08] are.

    Do the mean ratings of the two groups differ significantly from each other? And from what can this be inferred?

    2. FALSE: Yes, because the number 0.05 lies within the interval.
    3. FALSE: No, because the number 0.05 lies within the interval.
