Question

3. Honeybees returning from foraging convey information to bees in the hive about the location of food resources. One way they do this is through a waggle dance that other bees watch. Another way they convey information is by regurgitating some of the food they have collected to other bees, a process known as trophyllaxis. You are interested in the speed at which bees find a resource another bee "tells" them about. You decide to compare bees that have only observed a dance with bees that have observed a dance and accepted regurgitated food. You mark a lot of bees with bee tags (little numbered discs that you glue to the back of the thorax). This enables you to watch the same individual repeatedly. One day you choose a lot of bees that have seen a waggle dance but not accepted food. You measure (in seconds) how long it takes for them to find the resource. A week later you go back to the hive, and find the same individuals. This time you watch until they see a dance and accept food, and again measure how long it takes them to reach the resource. Here are your data. The numbers are seconds needed for the bee to reach the resource.

What is the test statistic? The table statistic? C. You decide that a bee that has both watched and gotten food from another bee finds the resource faster than one that has just watched, What other factor that is a result of vour experimental protocol might also explain your results?
