A National Center for Health Statistics survey suggested that, in the late 1970s, the mean serum cholesterol level in men was u = 210 mg/dL with standard deviation o = 90 mg/dL. You are interested to see if the mean serum cholesterol level in men is higher than 210. You sample n = 36 men from the population and are willing to assume that the sampling distribution of is approximately Normal. The sample mean, xbar, is 240 and the sample standard deviation. What is the alternative hypothesis? Ο Ha: μ > 210 На: д + 210 None of the above O Ha: µ < 210
