A quantitative variable contains 10 observations that have a mean value of 25. One of the 10 observations is recorded incorrectly and is changed from a value of 10 to a value of 20. The new mean is
----
Original mean = 25
Original total points = 10*25 = 250
-----
10 points are added to the total giving 260 points
New mean = 260/10 = 26
