The number of emergency calls per day at a hospital over a period of 120 days is shown below. Use α = .05 and the p-value approach to see if the above data have a Poisson distribution.
To investigate whether or not sending text messages while driving impacts driving ability,we had 100 participants (50 men and 50 women)drive an obstacle course under one of the following conditions: 1)no texting while driving,2)sending five text messages while driving,or 3)sending 10 text messages while driving.We measured the accuracy with which the subjects drove the obstacle course from a scale of 1 to 10 (1 = poor and 10 = excellent).Explain how you would randomize this study.
Randomly split subjects into three groups.Then randomly assign each group to a treatment.
