An experiment is conducted to estimate the difference in work productivity for employees under two conditions: with and without music playing in the background. Twenty employees volunteered to be part of the study. Ten of the volunteers were randomly assigned to work for one week with music playing in the background. The other 10 volunteers worked for one week without music playing in the background. Productivity is measured by counting the number of units produced for the week. Here are dotplots, which display the data: (See attached image)
The conditions for inference have been met. What is the correct 99% confidence interval for the difference in the population means (without – with)?
A. (1.370, 7.430)
B. (1.445, 7.355)
C. (1.525, 7.275)
D. (1.597, 7.203)
