Conduct a test at the alpha = .01 level to determine if this is true. For this test, consider a sample size of 30 households. Also, you want to have strong evidence to disclaim his hypothesis.
b) Find the probability of a Type two error when U = 2200.
c) Conduct the same test as in part a, however, use sampling data by taking the fist 50 data points in the population
d) Conduct a test at the alpha = .05 level to determine if there is a difference between taxes paid in neighborhood 1 and in neighborhood 4. Use all the data points from both neighborhoods and consider this to be sample data.
e) From part d, what is the 95% confidence interval for the difference between means.
