Heights were measured for a random sample of 18 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 37 centimeters and 9 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean μ. Based on the sample, can it be concluded that is different from 36 centimeters? Use the 0.05 level of significance. Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
