1. 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 $32.00. 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 accompanying table 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 $62.00, what should be
concluded based on the sample data? Test using =0.05. Click the icon to view the data table.
