1.A company manufactured six television sets on a given day, and these TV sets wereinspected for being good or defective. The results of the inspection follow.Good, Good, Defective, Defective, Good, Good.Show all possible samples of size four. Let p be the sample proportion of goodtelevision sets.a. Find the sampling distribution of p.b. Based on the sampling distribution in part a, find the mean of p (i.e., µg) usingthe formula 4g = E(p) = Ep P(p).

Let's examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 by drawing samples from these values, calculating the mean of each sample, and then considering the sampling distribution of the mean. To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…
