Question

In a study to assess the effects of malaria infection on mosquito hosts, mosquitoes were fed on either infective or non-infective rhesus monkeys. Subsequently the distance they flew during a 24 hr period was measured using a flight mill. The mosquitoes were divided into four groups of eight mosquitoes each. The summary data values are: T1: 1 X =4.39; T2: 2 X =4.52; T3: 3 X =5.49; T4: 4 X =6.36    c i n j ij j X 1 1 2 =911.91 Use the ANOVA F test at level .05 to decide whether or not there are any differences between true average flight times for the four treatments.
