a population consists of five numbers 1, 3, 5, 7 and 9. take all possible samples of size 3 without replacement from this population construct sampling distribution of sample mean find its mean and variance |

Answer» Acc to the question, the population CONSISTS of five numbers 2 3 6 8 11. Therefore, Mean(µ) = = 6.0 Standard deviation(σ) = = 10.8 Mean of the sampling DISTRIBUTION = (SUM of all SAMPLES)/25 = 150/25 = 6.0 [form a matrix of elements from the set of numnbers given and finally calculate its sum] Standard deviation of the sampling distribution = subtract the mean 6 from each number, square the result, ADD all 25 numbers obtained, and divide by 25. = 135/25 = 5.4Explanation: |
