Get a similar question You can retry this question below 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 54 51 63 66 46 51 Sprout Percent 58.5 70 69.5 55.5 61 67 72.5 a. Find the correlation coefficient: T = Round to 2 decimal places. b. The null and alternative hypotheses for correlation are Ho : 2 v = 0 H1 : 2 70 The p-value is: (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 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. 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. 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. OThere 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. a. The equation of the linear regression line is: y = ac + (Please show your answers to two decimal places) b. Use the model to predict the percent of seeds that sprout if the plant produces 52 seeds. Percent sprouting = (Please round to two decimal places.)
