"ANS" KEYS FOR 2-VARIABLE STATISTICS

In addition to the 1-variable statistic keys, the following keys have been added for calcu-
lating 2-variable statistics.
Calculates the sum of the product for sample data x and sample data y.
Calculates the sum of the data (sample data y).
Calculates the sum of the data (sample data y) raised to the second power.
Calculates the average value of the data (sample data y).
Calculates the standard deviation for the data (sample data y).
Calculates the standard deviation of a data population (sample data y).
NOTE:
The codes for basic statistical quantities of sample data x and their meanings
are the same as those for single-variable statistical calculations.
Let' s check the results based on the previous data.
