Suppose a paper reported that the freshman year weight gain for the students in a representative sample of 103 freshmen at a midwestern university was 5.6 pounds and that the standard deviation of the weight gain was 6.9 pounds. The authors also reported that 75.7% of these students gained more than 1.3 pounds, 17.4% maintained their weight within 1.3 pounds, and 6.8% lost more than 1.3 pounds. C) Calculate a 95% confidence interval (in pounds) for the population mean weight gain of freshmen students at this university. (Round your answers to three decimal places.)
