It is known that 60% of all brand a external hard drives work in a satisfactory manner throughout the warranty period (are "successes"). suppose that n = 15 drives are randomly selected. let x = 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 x/n is 0.2, corresponding to x = 3. what is the probability of this value (what kind of random variable is x)? ] (round your answers to three decimal places.)
