Yes, because 300 is in the confidence interval Question 15 points The director of admissions at the University of Maryland, University College is concerned about the high cost of textbooks for the students each semester. A sample of 25 students enrolled in the university indicates that x(bar) = \$315.40 and s = \$75. (Note the sample standard deviation is different from the first part). Using the .05 level of significance, is there evidence that the population mean is above \$300? 6 / 6 No, because 300 is below the lower limit of the confidence interval Yes, because 300 is below the lower limit of the confidence interval No, because 300 is in the confidence interval Yes, because 300 is in the confidence interval

The smaller standard deviation adds uncertainty in the sample. The sample may have had some outliers.
