The owner of the House of Greens Greenhouse wants to estimate the mean height that her seedlings grow. A sample of 14 plants were chosen and their growth was recorded over a period of a month. It was found that the sample mean was 20.00 cm and the sample standard deviation was 4.66 cm. Given this information, develop a 99.0% confidence interval estimate for the population mean (assuming the best point estimate for the population mean is the sample mean).
For full marks your answer should be accurate to at least three decimal places.
