Question

Jule hlh a value of X 21 is removed from the population, then what is the value of the new population mean? w1% A sample of n-bscores has a mean of M-I4. After one new score is added, the new sample has a mean 01 M=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. 4 18. For the following sample of n 10 scores: 2, 3,4,4, a. Assume that the scores are measurements of a h. Assume that the scores are measurements of a 5, 5, 5, 6, 6,7 discrete variable and find the modian. rontinvous variable and find the median by

Explanation / Answer

here let new score is X.

therefore total score of 7 numbers =X+14*6=X+84

now new mean =(X+84)/7 =12

X+84 =12*7

X=84-84

X =0

therefore new added score is 0/
