To select linear regression and input the following data:
(170, 66), (173, 68), (179, 75)
N3(STAT)2(A+BX)
170 = 173 = 179 =ce
66 = 68 = 75 =
Important: • All data currently input in the Stat Editor is deleted whenever
you exit the STAT Mode, switch between the single-variable and a paired-
variable statistical calculation type, or change the Stat Format setting on
the setup menu. • The following operations are not supported by the Stat
Editor: m, 1m(M–), 1t(STO). Pol, Rec, ÷R, and multi-statements
also cannot be input with the Stat Editor.
To change the data in a cell: In the Stat Editor, move the cursor to the cell
that contains the data you want to change, input the new data, and then
