A service company recently revised its call-routing procedures in an attempt to increase efficiency in routing customer calls to the appropriate agents. A random sample of customer calls was taken before the revision, and another random sample of customer calls was taken after the revision. The selected customers were asked if they were satisfied with the service call. The difference in the proportions of customers who indicated they were satisfied (p after−p before) was calculated. A 90 percent confidence interval for the difference is given as (−0.02,0.11). The manager of the company claims that the revision in the procedure will change the proportion of customers who will indicate satisfaction with their calls.
