To describe the center and spread of the above distribution, the appropriate numerical measures are:the mean and the medianthe mean and the standard deviationthe IQR and the standard deviationthe median and the IQRAny of the above would be appropriate, it is just a matter of taste.

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
