An electronic prize wheel is programmed to land on "win" 25% of the time on weekdays and 10% of the 5.time on weekends, and consecutive plays produce winners independently. Suppose we observe a random sample of 50 outcomes from this machine on weekdays and 100 outcomes from this machine on weekends. Let and be the sample proportions of winners on weekdays and weekends, respectively. Which of ppWD WE the following describes the shape, mean, and standard deviation of the sampling distribution of ?p pWD WE (a)Shape = approximately normal, mean = 0.15, standard deviation = 0.07 Shape = approximately normal, mean = 0.15, standard deviation = 0.05 (b)(c)Shape = approximately normal, mean = 0.35, standard deviation = 0.07 Shape = skewed right, mean = 0.35, standard deviation = 0.05 (d)(e)Shape = skewed right, mean = 0.35, standard deviation = 0.0
