SpletSolution: Given, the data is 26, 28, 25, x, 24 The mean of the data is 27. We have to find the value of x. Mean = Sum of all observations/Number of observations Sum of all observations = 26 + 28 + 25 + x + 24 = 50 + 53 + x = 103 + x Number of observations = 5 Mean = (103+x)/5 27 = (103+x)/5 103 + x = 27 (5) 103 + x = 135 x = 135 - 103 x = 32

So, The total sum of all the 25 observations = 27 x 25 = … Splet30. jan. 2024 · The answer is 27 mean = 27 sum of all observations = 27 *25 now when new observation is added then mean = 27 (remains same is given) sum of all observations = 27(25+1) now sibtract both the sums to get the added observation value 27*26 - 27*25 = 27 Hope it helped you. Let me know if any further doubt. Cheers !!! good team work gif
