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…

Meredith works at a blood bank. She needs to write a report of the ratio of type- a blood donated to tpye-o blood donated, but she lost this month's logs that had the quantities. She knows that last month 25 pints of tpye-a blood were donated and 42 pints of tpye-o blood were donated. She remebers that this month 55 pints of tpye-a blood were donated. if the ratio held true for this month, how can Meredith determine the amount of tpye-o blood donated
