Heights were measured for a random sample of 21 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 45 centimeters and 10 centimeters, respectively.Assume that the population of heights of treated plants is normally distributed with mean u. Based on the sample, can it be concluded that u is different from 40 centimeters? Use the 0.1 level of significance.Perform a two-tailed test. Then fill in the table below.
