The mean of 10 values is 25. Six of those values have a mean of 20. What is the mean of the remaining 4 values? Total sum=250, sum of 6=120, sum of 4=130, mean=130/4=32.5
Q1. The mean of 10 values is 25. Six of those values have a mean of 20. What is the mean of the remaining 4 values? Total sum=250, sum of 6=120, sum of 4=130, mean=130/4=32.5
Answer: 32.5
Explanation: Total sum = 10×25 = 250; sum of 6 values = 6×20 = 120; remaining sum = 130; mean of 4 = 130/4 = 32.5.
