b. Using technology construct a 99%
confidence interval.
Researchers are interested in the effect of a certain nutrient on the growth rate of plant seedlings. Using a hydroponics grow procedure that utilized water containing the nutrient, they planted six tomato plants and recorded the heights of each plant 14 days after germination. T heights, measured in millimeters, were 55.8, 59.6, 60.8, 63.6, 64.7, and 67.2 2. Complete parts a through d below. a. Using technology, find the 95% confidence interval for the population mean u. (OD) (Round to one decimal place as needed.)
