8. Heights were measured for a random sample of 9 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 34 centimeters and 11 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean u. a. Based on the sample, can it be concluded that μ is different from 38 centimeters? 0.05 level of significance. (don't forget to construct null and alternate Hypotheses) Find 95% confidence interval for population mean. Does your confidence interval support your result in part b. b.
