In order to construct a confidence interval for the population variance, a random sample of n observations is drawn from a normal population. Use this information to find χ2α/2,df and χ21-α/2,df under the following scenarios. (Round your answers to 3 decimal places. You may find it useful to reference the appropriate table: chi-square table or F table) χ2α/2,df χ21-α/2,df a. A 90% confidence level with n = 25. b. A 90% confidence level with n = 35. c. A 99%...
