Consider a data set containing the following values: 60 93 84 80 95 99 78 90 The mean of the preceding values is 84.875. The deviations from the mean have been calculated as follows: -24.875 8.125 -0.875 -4.875 If this is sample data, the sample variance is If this is population data, the population variance is 10.125 14.125 -6.875 5.125 and the sample standard deviation is and the population standard deviation is Suppose the smallest value of 60 in the data was misrecorded as 75. If you were to recalculate the variance and standard deviation with the 75 instead of the 60, your new values for the variance and standard deviation would be
