Question

An electronic prize wheel is programmed to land on "win" 25% of the time on weekdays and 10% of the 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 pwn
and iwn be the sample proportions of winners on weekdays and weekends, respectively. Which of the following describes the shape, mean, and standard deviation
of the sampling distribution of pWD - PWE?
O Shape = skewed right, mean - 0.35, standard deviation = 0.05
O Shape - approximately normal, mean 0.35, standard deviation - 0.07
O Shape = skewed right, mean - 0.35, standard deviation - 0.07
O Shape = approximately normal, mean - 0.15, standard deviation - 0.07
O Shape = approximately normal, mean -0.15, standard deviation - 0,05
