tRe biginal 0l 11. A sample of n 8 scores has a mean of M -7. If one score is changed from X -20 to X -4, what is the value of the new sample mean? mean? Asample of n = 5 scores has a mean of M=12.11 one new score with a value of X=18 is added to the sample, then what is the mean for the new sample? 13. Apopul ation of N-10 scores has a mean ol -12. If one score with a value of X-21 is removed from the population, then what is the value of the new population mean? 14. A sample of n 6 scores has a mean of M-14. After one new score is added, the new sample has a mean ofM=12, what is the value of the score that was added? 15. Apopulation of N-7scores has a mean of -9. After one score is removed, the new population has a mean of -10, what is the value of the score that was removed? 16. Find the median for the following set of scores: 1,9 3, 6,4,3, 11, 10 17. Find the median for the distribution of scores in the following frequency distribution table.Explanation / Answer
(12)
N = 5, M = 12
Sum of the scores = 5 * 12 = 60
New sum = 60 + 18 = 78
New N = 6
New M = 78/6 = 13
