Question

Question Help The assets (in billions of dollars) of the four wealthiest people in a particular country are 39, 25, 22, 17. Assume that samples of size n=2 are randomly selected with replacement from this population of four values a. After identifying the 16 different possible samples and finding the mean of each sample, construct a table representing the sampling distribution of the sample mean In the table, values of the sample mean that are the same have been combined Probability Probability 32 our 22 30.5 21.5 incorre ote 28 (Type integers or fractions.) om scu udy Enter your answer in the edit fields and then click Check Answer.

Answer 1

NO. No Population values (en $) are 39, 26, 22,17. Table showing all possible samples are as follows: serial sample values Serial Sample values a 39,39 39 22, 39 30.5 39, 26 32.5 10 22, 26 24 39, 22 22,22 130.5 22 39, 17 28 12 22,19 $19.5 26,39 32.5 13 19.39 28 26.26 26 17.26 26, 22 24 17.22 19.5 8 26. 17 21.5 16 17.17 17 11 21.5 15 As the samples are randomly selected, so each of the somble has the same chance of being selected Total no of all possible samples 16. so, each sample has the chance - of being selected. Now Pla=39) - P(139,393) - to [ Sample mean will be 39 when damble values are 39.397 Plž= 32.5) =P [ {39,26} or {26,39}] - Pl{39.26J + PL{2.6, 39}] = t - 2 Similarly it can be found for other values of c ' Thus, we have the following table. ď Probability Probability 39 - 24 32. 5 2 - 22 2 31 30.5 21.5 2 19.5
