I know it's a lot but I need help with a ,b,d, f and g. Thanks
pencol.instructure.com/courses/2221498/assignments/26333455?module_item_id=64273522 that produce a mixed number of secus, this variation on average i reuuced by UJN. O Given any group of plants that all produce the same number of seeds, 63% of all of these plants will produce seeds with the same chance of sprouting. OB f. The equation of the linear regression line is: Y (Please show your answers to two decimal places) g. Use the model to predict the percent of seeds that sprout if the plant produces 55 seeds. Percent sprouting = (Please round your answer to the nearest whole number.) 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 seeds that sprout since you cannot have a negative number. For every additional seed that a plant produces, the chance for each of the seeds to sprout tends to decrease by 0.89 percent. O As x goes up, y goes down. tercent in the context of the question: OF A Q

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 45 67 44 50 Sprout Percent 60.5 40.5 59 67 45 55.5 57 54 43.5 55 a. Find the correlation coefficient: r Round to 2 decimal places. b. The null and alternative hypotheses for correlation are: Ho: p 0 H₁: p ✓ #0 700 OF The p-value is: t (Round to four decimal places) c. Use a level of significance of a = 0.05 to state the conclusion of the hypothesis test in the context of the study. 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. There is statistically insignificant 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 use of the regression line is not appropriate. 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. 7.2 = (Round to two decimal places) d.
