(Round to two decimal places) d. e. Interpret r: O There is a 67% chance that the regression line will be a good predictor for the percent of see that sprout based on the number of seeds produced. O There is a large variation in the percent of seeds that sprout, but if you only look at plants th produce a fixed number of seeds, this variation on average is reduced by 67%. O 67% of all plants produce seeds whose chance of sprouting is the average chance of sprouting O Given any group of plants that all produce the same number of seeds, 67% of all of these plar will produce seeds vrith the same chance of sprouting. f. The equation of the linear regression line is: (Please show your answers to two decimal places) g. Use the model to predict the percent of seeds that sprout if the plant produces 58 seeds. (Please round your answer to the nearest whole number.) Percent sprouting = h. Interpret the slope of the regression line in the context of the question: O The slope has no practical meaning since it makes no sense to look at the percent of the seed that sprout since you cannot have a negative number. O As x goes up, y goes down. O For every additional seed that a plant produces, the chance for each of the seeds to sprout tends to decrease by 0.71 percent. i. Interpret the y-intercept in the context of the question: O The average sprouting percent is predicted to be 97.6. Olf plant produces no seeds, then that plant's sprout rate will be 97.6. O The best prediction for a plant that has 0 seeds is 97.6 percent. O The y-intercept has no practical meaning for this study.
