Joe has two routes he can drive to work. He wants to learn which route is the fastest. The time to drive each route varies a little every day.Joe assumes that each route will be open and safe to drive. Over the next two weeks Joe alternated driving the two routes. He timed the length of his drive on each route.He calculated the mean and standard deviation of the times for both routes. Route 1Route 2Mean25.2 minutes25.8 minutesStandard Deviation1.8 minutes8.9 minutes Joe chose a route. Under which of the following circumstances should Joe re-evaluate his decision? (Mark all that apply)Group of answer choicesThe installation of traffic lights on the route he has chosen.The number of vehicles on the routes change.Joe changes job locations.Road construction on the route he has chosen.

Joe should re-evaluate his decision under the following circumstances:

1. The installation of traffic lights on the route he has chosen: This could potentially increase the time it takes for him to get to work due to increased stops and waiting times.

2. The number of vehicles on the routes change: If there is an increase in the number of vehicles on his chosen route, this could lead to more traffic and thus a longer commute time. Conversely, if the number of vehicles decreases, his commute time could potentially decrease.

3. Joe changes job locations: If Joe's job location changes, the routes and their respective times will likely change as well. He would need to re-evaluate his decision based on the new routes and times.

4. Road construction on the route he has chosen: Road construction could lead to detours and increased traffic, thus increasing his commute time. He should re-evaluate his decision if construction begins on his chosen route.
