A study was conducted to explore the possibility of a audiobook treatment effect on sleep quality (better, worse). One version of the study involved 30 professional clowns. The professional clowns were given the option to choose which group they were in. One group listened to an audiobook while they slept, while the other group did not. The researchers found a difference of 28.4 percentage points between the proportion of professional clowns in each group who experienced worse sleep quality. The group that listened to an audiobook had the higher proportion. The tail proportion from a randomisation test carried out with the data from the study was 122/1000. Use the information above to answer the following questions. In some cases, you will need to copy and paste words exactly as they appear above. Who were the participants in this study? How many participants were used for this study? What was the treatment effect explored? treatment effect What was the level of focus for the categorical response variable? Write the tail proportion as a percentage (rounded to one decimal place e.g. 12.5 or 25.0): % Is the observed difference compatible with the null model? (enter yes or no) Is the observed difference unusual when compared to the 'just chance' distribution? (enter yes or no) Was randomisation used in the design of the study? (enter yes or no)
