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   If this is sample data, the sample variance is      and the sample standard deviation is     .   If this is population data, the population variance is      and the population standard deviation is     .   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     .

Question
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
 
If this is sample data, the sample variance is      and the sample standard deviation is     .
 
If this is population data, the population variance is      and the population standard deviation is     .
 
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     .
