Question

A biologist looked at the relationship between number of seeds a plant produces and the percent of those seeds that sprout. The results of the survey are shown below.

Seeds Produced	63	62	43	43	58	59	67	61
Sprout Percent	55.1	62.4	64.1	74.1	63.6	66.3	51.9	64.7

Use the model to predict the percent of seeds that sprout if the plant produces 50 seeds.
Percent sprouting = (Please round your answer to the nearest whole number.)
Interpret the slope of the regression line in the context of the question:
- The slope has no practical meaning since it makes no sense to look at the percent of the seeds that sprout since you cannot have a negative number.
- As x goes up, y goes down.
- For every additional seed that a plant produces, the chance for each of the seeds to sprout tends to decrease by 0.55 percent.
Interpret the y-intercept in the context of the question:
- The average sprouting percent is predicted to be 94.37.
- The best prediction for a plant that has 0 seeds is 94.37 percent.
- If plant produces no seeds, then that plant's sprout rate will be 94.37.
- The y-intercept has no practical meaning for this study.
