On Stubhub, the top best value tickets available cost: 187, 323, 210, 215, 302, 201, 190, 250, and 250. Calculate the variance. Here, indicate what the sum of the difference from the mean squared value is for this dataset (i.e., the numerator for the variance equation). Round to the nearest tenths place.
Calculate the mean, median, mode, range, variance and standard deviation for the sample. Calculate SS, variance, and standard deviation for the following sample of n = 5 scores: 2, 9, 5, 5, 9 Note: The definitional formula for SS works well with these scores.

A citizen in search of work sent to three different organizations, probability of getting an invitation to the interview from the first company equals 0.1 from the second one-0.6 and from the third one - 0.3 find the main value variance, mean square deviation, mide and median of the number of companies, given the positive answer
Harley Davidson claims their mean decibel rating on bikes is 70 with a variance of 10. The variance of the noise is questioned. Just because Harley has a mean that is less than 80, they could still be producing louder than acceptable bikes. The federal EPA conducts a sample of 30 bikes and determines the variance to be 20 decibels.
