Consider a data set containing the following values: 80, 94, 93, 106, 91, 90, 96, 99The 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, 5.375If this is sample data, what is the sample variance? What is the sample standard deviation? If this is population data, what is the population variance? What is the population standard deviation?Suppose the largest value of 106 in the data was misrecorded as 100. If you were to recalculate the variance and standard deviation with the 100 instead of the 106, your new values for the variance and standard deviation would be...
