The arithmetic mean of 100 numbers was computed as 89.05.It was later found that two numbers 92 and 83 have been misread as 192 and 33 respectively.What is the correct arithematic mean of numbers?70.5576.0288.5592.34

The mean of 200 values of a data was 50. It was later found that two values were wrongly readas 92 and 8 instead of 192 and 88 respectively. The correct mean is:

25 numbers were recorded and their average was calculated as 50.6. Later it was found that three numbers 29, 35, and 72 were wrongly taken as 92, 53 and 27 respectively, and one number 58 was inadvertently left out from being recorded. What is the correct average of all the numbers?

The mean of 100 observations was calculated as 69. It was found later on that one of the observations was misread as 92 instead of 67. The correct mean is: Options :69.2568.2567.75none of these

If the arithmetic mean of 10, 20, 30, 40, 50, …, 180, 190 and 200 is 105, then the arithmeticmean of 20, 40, 60, 80, 100 …, 360, 380 and 400A. is 105B. is 115C. is 210D. cannot be determined

The mean of 40 numbers is 37.5. If one of these numbers is taken as 53 instead of 35, then the correct mean is ________________
