KeysDescription

v¡	Opens editor for reviewing/editing
	statistical data.
\k \«	Means of x and y.
\T \«	Mean of x weighted by y. Also
	calculates b, coefficient.
\h \«	Sample standard deviations of x and
	y.
\e \«	Population standard deviations of x
	and y.
y-data \Z \«	Estimate of x and correlation
	coefficient.
x-data \W \«	Estimate of y, slope and m coefficient.
]L	Permits selection of six regression
	models or a best fit. Default is linear.

Using the following data, find the means of x and y, the sample standard devia- tions of x and y, and the y-intercept and the slope of the linear regression fore-

cast line. Then, use summation statistics to find Σ xy.
