Note: While single-variable statistical calculation is selected, you can input the functions and commands for performing normal distribution calculation from the menu that appears when you perform the following key operation: 11(STAT/DIST) 5(Distr). See “Performing Normal Distribution Calculations” for details.

To input the single-variable data x = {1, 2, 2, 3, 3, 3, 4, 4, 5}, using

the FREQ column to specify the number of repeats for each items

 

({xn; freqn} = {1;1, 2;2, 3;3, 4;2, 5;1}), and calculate the mean and population standard deviation.

To calculate the linear regression and logarithmic regression

correlation coefficients for the following paired-variable data and

 

determine the regression formula for the strongest correlation: (x, y) = (20, 3150), (110, 7310), (200, 8800), (290, 9310). Specify Fix 3 (three decimal places) for results.
