A college professor claims that the entering class this year appears to be smarter than entering classes from previous years. He tests a random sample of 13 of this year's entering students and finds that their mean IQ score is 119, with standard deviation of 11. The college records indicate that the mean IQ score for entering students from previous years is 112. If we assume that the IQ scores of this year's entering class are normally distributed, is there...
