I have trouble with sampling distribution. I don't get this question

5. 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 Pwo and PWE 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? (a) Shape = approximately normal, mean # 0.15, standard deviation = 0.07 (b) Shape = approximately normal, mean 0.15, standard deviation = 0.05 (c) Shape = approximately normal, mean # 0.35, standard deviation = 0.07 (d) Shape = skewed right, mean - 0.35, standard deviation = 0.05 (e) Shape = skewed right, mean - 0.35, standard deviation - 0.07 A local news story claims that 53% of high school males agree with the statement "I am ok with a girl rls " To investigate this claim, an S
