For these 30 watermelons, you also measured the circumference (distance around the watermelon in the largest spot). You want to see if there is a relationship between the circumference and the weight of the watermelon. Complete each of the following. You must make all calculations by hand. I have included a table if that is helpful for you on the next page. When making all calculations you MUST round to 1 decimal place and round your answers to 1 decimal place as well. If you do not round as indicated, you will not receive credit for your answers. When completing this phase ofthe project use the following values for the mean and standard deviations for the weight and circumference of the watermelons. Weight (y) l Mean 21.0 | Standard Deviation 3.3 Circumference (x) 31.8 7.2 0 Calculate r (circumference being at and weight being y), based on Table II is there a linear relationship (explain) 0 Graph, be sure to label axis and title no technology graphs accepted, must be completed by hand Watermelons
