In order to construct a confidence interval for the population variance, a random sample of n observations is drawn from a norma population. Use this information to find x²a/2, df and x²1-a/2, df under the following scenarios. (Round your answers to 3 decima places. You may find it useful to reference the appropriate table: chi-square table or Ftable) X²1-a/2,df a. A 95% confidence level with n = 9. b. A 95% confidence level with n = 40. A 000 ofidence level with X²a/2,df
