Fiting a straight line to a set of data yields the prediction line Y^1=5+9X1. The values of X used to find the prediction line range from 5 to 24 ) a. Should this model be used to predict the mean value of Y when X equals 6 ? b. Should this model be used to predict the mean value of Y when X equals -6 ? c. Should this model be used to predict the mean value of Y when X equals 0? d. Should this model be used to predict the mean value of Y when X equals 23? a. Should this model be used to predict the mean value of Y when X equals 6 ? Yes No Not enough information b. Should this model be used to predict the mean value of Y when X equals -6 ? Yes No Not enough information c. Should this model be used to predict the mean value of Y when X equals 0 ? Yes No Not enough information d. Should this model be used to predict the mean value of Y when X equals 23? Yes No Not enough information
