An article that appeared in the British Medical Journal (2010) presented the results of a randomized experiment conducted by researcher Jeremy Groves, whose objective was to determine whether the weight of his bicycle could affect his travel time to work. On each of 56 days (from mid-January to mid-July 2010), Groves tossed a £1 coin to decide whether he would be biking to work on his carbon frame (lighter) bicycle that weighed 20.9 lbs or on his steel frame (heavier) bicycle that weighed 29.75 lbs. He then recorded the commute time (in minutes) for each trip. Here are the summary statistics for his data: Bike Type Sample size Sample average Sample SD Carbon frame (lighter) 26 108.34 min 6.25 min Steel frame (heavier) 30 107.81 min 3.89 min Which of the following applets would be most appropriate to use, in the context of this study? One Mean One Proportion Multiple Proportions Multiple Means Matched Pairs

Question
An article that appeared in the British Medical Journal (2010) presented the results of a randomized experiment conducted by researcher Jeremy Groves, whose objective was to determine whether the weight of his bicycle could affect his travel time to work. On each of 56 days (from mid-January to mid-July 2010), Groves tossed a £1 coin to decide whether he would be biking to work on his carbon frame (lighter) bicycle that weighed 20.9 lbs or on his steel frame (heavier) bicycle that weighed 29.75 lbs. He then recorded the commute time (in minutes) for each trip.
Here are the summary statistics for his data:
| Bike Type | Sample average | Sample SD | |
| Carbon frame (lighter) | 26 | 108.34 min | 6.25 min |
| Steel frame (heavier) | 30 | 107.81 min | 3.89 min |
Which of the following applets would be most appropriate to use, in the context of this study?
One Mean
