Card 43 / 180: A new dental office opens in the town of Newsville. The owners of the dental practice decided to locate in Newsville based on the assumption that the new practice would see an average of 35 patients a month in the first year of business. After three months in business, the owners confidentially conclude they underestimated the average by more than 20 patients and think they should open a second location in town. However, the average for the first 3 months is a clerical error, and in truth, they have averaged just about 35 patients a month. The dental office's clerical error is an example of which of the following?
A) A Type I error
B) A Type II error
C) Both a Type I and a Type II error
D) The power of the hypothesis test
