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…
