Document Summary
Summer session i, 2015: a large (hypothetical) study of the relationship between parental income and iqs of their children yielded the following statistics. average income , 000, sd , 000 average iq 100, Sd 15, r 0. 5 (a) (4 pts) find the regression equation that predicts iq from income from this data. Intercept: 0 = iq 1 inc = 100 1. 90, 000 = 85 (b) (2 pts) find the r. m. s. error (ser) of regression for the regression in part (a). Include a margin of error (a plus/minus" number) with your estimate. The predicted iq for the child of parents with an income of , 000 is (cid:99)iq(150, 000) ser = 85 + 150, 000 13 = 110 13. In other words, we expect such a child to have an iq between 97 and 123: a standard, six-sided die is rolled three times. (a) (2 pts) what is the probability that all three rolls result in or.
