b) The Office of National statistics report that the average duration of unemployment for working age adults was twenty weeks in the North of England, with a population standard deviation of five weeks. This compared to a duration of sixteen weeks, with a population standard deviation of six weeks in the South of England. Assume a sample size of one hundred in both regions. What is the probability of a sample of one hundred having a mean within one week of the population mean for: 1) the North of England, and 2) the South of England? Comment on your findings 10 marks
