Directions: Construct at least two examples of PROBLEM-APPLICATIONS on point and interval- estimate following the pattern given below: (30 points each) NOTE: Make sure that one problem-application begins with raw data for you to compute for the population mean, sample mean and standard deviation while the other application directly provides values of the point-estimate (sample mean), standard deviation and significance level. A. Statement of the Problem B. Formulas to be used C. Computations and Solutions
