The Journal de Botanique reported that the mean height of Begonias grown while being treated with a particular nutrient is36 centimeters. To check whether this is still accurate, heights are measured for a random sample of16 Begonias grown while being treated with the nutrient. The sample mean and sample standard deviation of those height measurements are39 centimeters and9 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 height of treated begonias,?, is different from that reported in the journal? Use the0.05 level of significance.Perform a two-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places.
Question 18 of 20 (1 point) | Question Attempt: 1 of 1 of treated begonias, u, is different from that reported in the journal? 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. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H. O P H : 0 X S P H : 0 (b) Determine the type of test statistic to use. (Choose one) 0=0 030 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) 070 00 0 (d) Find the p-value. (Round to three or more decimal places.) X ? (e) Can it be concluded that the mean height of treated Begonias is different from that reported in the journal? OYes ONo Save
