Q2. A random sample of 35 people is selected in Netherlands and it is found that a typical person drinks 70 liters of beer per year. The standard deviation of the yearly beer consumption is estimated as 5. Under the assumption that beer consumption is normally distributed Construct 99% confidence interval for the mean beer consumption. Test the alternative hypothesis that average beer consumption is different а) b) than 70 by setting a=0.01. State your conclusion also in words. c) hypothesis testing and confidence interval. d) Based on your answers in part (a) and (b), comment on the relation between Suppose that in reality, the average beer consumption is 82 liters. Calculate the type 2 error probability using a significance level of 0.01.
