It is known that 80% of all brand a dvd players work in a satisfactory manner throughout the warranty period (are "successes"). suppose that n ¼ 10 players are randomly selected. let x ¼ the number of successes in the sample. the statistic x/n is the sample proportion (fraction) of successes. obtain the sampling distribution of this statistic. [hint: one possible value of x/n is .3, corresponding to x ¼ 3. what is the probability of this value (what kind of random variable is x)? ]
