Reseаrchers аre interested in the effect оf distrаctiоns оn work efficiency. Forty college students volunteered to be part of an experiment in which half were randomly assigned to a quiet room and the other half to a room in which loud music was playing. The students were asked to complete an easy Sudoku puzzle and their completion times were recorded. A 95% confidence interval for the difference between mean completion times for the puzzle (music - no music) was found to be (5, 11) minutes. Could this information be used to conclude that we should reject a null hypothesis of no difference in the average completion time between these two groups at a significance level of 0.05?
