A B D Problem #2 Confidence Interval and Hypothesis Testing (20 points) At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $40.00. Other bank managers at the meeting suggested that this statement may be in error and that it might be worthwhile to conduct a test to see if there is statistical support for the call center manager's statement. The following MS Excel data file, BBUS 215 Past Due Amounts-1.xIsx contains data for a random sample of 67 customers from the call center population. Assuming that the population standard deviation for past due amounts is known to be $64.00, download the data set, open it in SPSS, explore the data (sample mean and sample standard deviation), create a 90% confidence interval, and run the appropriate test statistic. What should be concluded based on the sample data? Test using a=0.10. (Use SPSS to explore the data and create the confidence interval and complete the hypothesis test and copy and paste your SPSS outputs in the space provided.)\f
