What is the Sample Mean ? b.) Fill in the blanks in the table below to help solve for the Standard Deviation of the sample. X x - I) (x - X 2 2 7 7 10 10 12 15 15 20 20 14 14 c.) Find the Standard Deviation of the sample **Round to TWO decimal places** d.) If the data was Population Data, instead of Sample Data, what would happen to the Mean of the data? O The Mean would Decrease O The Mean would Increase O The Mean would remain the same e.) If the data was Population Data, instead of Sample Data, what would happen to the Standard
