A scientist investigated the effect of cross-fertilization on the heights of plants. In one study, the scientist planted 15pairs of a species of plant. Each pair consisted of one cross-fertilized plant and one self-fertilized plant grown in the same pot. The table available below gives the height differences, in eighths of an inch, for the 15 pairs. Each difference is obtained by subtracting the height of the self-fertilized plant from that of the cross-fertilized plant. Use the paired t-interval procedure to determine a 99% confidence interval for the difference between the mean heights of cross-fertilized and self-fertilized plants. Interpret the result. (Note: d=19.00 and sd=35.50.) The 99%confidence interval is from eighths of an inch to_ eighths of an inch. (Round to two decimal places as needed. Use ascending order.) Which statement below best interprets the confidence interval? A. There is 99%confidence that the difference between the mean heights of cross-fertilized plants and self-fertilized plants is in the interval. B. There is 99%confidence that a pair of cross-fertilized and self-fertilized plants has a difference in heights that is in the interval. C. There is 99%confidence that the difference between the heights of cross-fertilized and self-fertilized plants is in the interval. D. There is 99%confidence that the difference between the heights of a cross-fertilized plant and a self-fertilized plant is in the interval.
