Question

Three randomly selected households are surveyed. The numbers of people in the households are 3, 4, and 11. Assume that samples of size n=2 are randomly selected with replacement from the population of 3, 4, and 11. Listed below are the nine different samples. Complete parts (a) through (c). 3,3 3,4 3,11 4,3 4,4 4,11 11,3 11,4 11,11 a. Find the median of each of the nine samples, then summarize the sampling distribution of the medians in the format of a table representing the probability distribution of the distinct median values. Sample Median Probability 7 (Type integers or fractions. Use ascending order of the sample medians.)
