Their model is cheerios = 0.56 + 5.11(diameter) The slope of this model is best interpreted in context as... For every 5.11 inches of diameter, the circumference is about 1 cheerio bigger. O For every 1 inch of diameter, the circumference holds about 0.56 more cheerios. It takes 5.11 cheerios to fill a plate's circumference. O .For every 1 inch of diameter, the circumference holds about 5.11 more cheerios. A mistake, because it is about 3.14 and that should be the slope.A company studying the productivity of its employees on a new information system was interested in determining if the age (X) of data entry operators influenced the number of completed entries made per hour (Y).
