Systemic vascular resistance determinations were made on a sample of 16 patients with chronic, congestive heart failure while receiving a particular treatment. The sample mean and standard deviation were 1600 and 700, respectively. a- Calculate the 95% Confidence Interval of the population mean. b- At the .05 level of significance do these data provide sufficient evidence to indicate that the population mean is less than 2000?
