12.3

23.6

36.7

47.2

511

• First, enter the two columns of data into variable ΣDAT by using the matrix

. The output from this program,

shown below for our particular data set, consists of the following three

lines in RPN mode:

3: '0.195238095238 + 2.00857242857*X'

2: Correlation: 0.983781424465

1: Covariance: 7.03
