A mathematics teacher wanted to see the correlation between test scores and homework. The homework
grade (x) and test grade (y) are given in the
accompanying table. Write the linear regression
equation that represents this set of data, rounding all
coefficients to the nearest hundredth. Using this
equation, find the projected test grade, to the nearest
integer, for a student with a homework grade of 49.

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
