Consider a data set containing the following values: 80, 94, 93, 106, 91, 90, 96, 99 The mean of the preceding values is 93.625. The deviations from the mean have been calculated as follows: –13.625, 0.375, –0.625, 12.375, –2.625, –3.625, 2.375, 5.375 (a) If this is sample data, the sample variance is ___ and the sample standard deviation is ___. (b) If this is population data, the population variance is ___ and the population standard deviation is ___. (c) Suppose the smallest value of 80 in the data was misrecorded as 8. If you were to recalculate the variance and standard deviation with the 8 instead of the 80, your new values for the variance and standard deviation would be ___ and ___.
