Question 45 1 pts For Q48-Q56 : A researcher wants to know whether the amount of stress is different for three groups of employees. Employees in group 1 work in the night shift (4PM-Midnight). Employees in group 2 work in the morning/day shift (Midnight-8AM) and employees in group 3 work in the day/evening shift (8AM-4PM) Descriptives the stress level from 1 to 10 95% Confidence Interval for Std.

Which group has the lowest mean of stress level? O Night shift (4pm-midnight) O Morning/day shift (midnight-8pm) Day/evening shift (8am-4pm) O No sufficient informationQuestion 46 1 pts What is the average stress level of all groups? O 6.30 o 5.00 o 3.85 O 4.94 Question 47 1 pts How many total observations are in the sample? 033 O35 O36 037 Question 48 1 pts How many groups are in the sample? 01 02 O3 O4 \fQuestion 52 1 pts What would be an appropriate conclusion? 0 There is supporting evidence from the sample that there is different in the mean of stress among shifts. Q There is supporting evidence from the sample that at least one shift is different in the mean of stress from other shifts. 0 There is no supporting evidence from the sample that there is different in the mean of stress among shifts. 0 There is no supporting evidence from the sample that at least one shift is different in the mean of stress from other shifts. Question 53 1 pts Based on the multiple comparison (Post Hoc) using Bonferroni method, which pair of shifts does have the difference in mean of stress? 0 Night shift - Morning/ Day shift 0 Morning/Day shift - Day/Evening shift 0 Night shift - Day/ Evening shift 0 None above
