The Journal de Botanique reported that the mean height of Begonias grown while being treated with a particular nutrient is 36 centimeters. To check whet this is still accurate, heights are measured for a random sample of 18 Begonias grown while being treated with the nutrient. The sample mean and sample standard deviation of those height measurements are 40 centimeters and 7' centimeters, respectively. Assume that the heights of treated Begonias are approximately normally distributed. Based on the sample, can it be concluded that the population mean i of treated begonias, p, is different from that reported in the journal? Use the 0.10 level of signicance. Perform a twotailed test. Then complete the parts below. Carryr your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1. H0 :I: H1 :I: (b) Determine the type of test statistic to use. [Choose one)
