The null and akernative hypotheses for correlation are: The p-value is: 0.0407 e (Round to four decimal places) C Use a level of significance of ÔI = 0.05 to state the conclusion of the hypothesis test in the context of the study. O There is statistically insignificant evidence to conclude that a plant that produces more seeds will have seeds with a lower sprout rate than a plant that produces fewer seeds. O There is statistically significant evidence to conclude that a plant that produces more seeds will have seeds with a lower sprout rate than a plant that produces fewer seeds. O There is statistically significant evidence to conclude that there is a correlation between the number of seeds that a plant produces and the percent of the seeds that sprout. Thus, the regression line is useful.

Interpret r O There is a 47% chance that the regression line will be a good predictor for the percent of seeds that sprout based on the number of seeds produced, O There is à large variation in the percent of seeds that sprout, but if you only look at plants that produce a fixed number of seeds, this variation on average is reduced by 47%. O 47% 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, 47% of all of these plants will produce seeds with the same chance of sprouting. f. The equation of the linear regression line s: (Please show your answers to two decimal places) g. Use the model to predict the percent of seeds that sprout if the plant produces 56 seeds. Percent sprouting (Please round your answer to the nearest whole number.) h. Interpret the stope of the regression line in the context of the question: For every additional seed that a plant produces, the chance for each of the seeds to sprout tends to decrease by 0.50 percent. The slope has no practical meaning since it makes no sense to look at the percent of the seeds that spIOal since you Cannot have a nepative number. esc F5 F6 F7 F1 F2 F3 F4 #3 $ & 1 Q W 2
