Question 31 options: A library system lends books for periods of 21 days. This policy is being reevaluated in view of a possible new loan period that could be either longer or shorter than 21 days. To aid in this decision, book-lending records were consulted to determine the loan periods actually used by the patrons. A random sample of n = 8 records revealed the following loan periods in days: 21 15 12 24 20 21 18 16 Is there a difference between the current library system of µ = 21 days and the sample taken above? Assume α=.05 for a 2-tailed test. Report your results in APA style. Round all values to 2 decimal places. If indicating significance please use one of the following two symbols: > to indicate greater than or </= to indicate less than or equal to. We do not have sufficient evidence to conclude that the new library system (M = , SD = ) is significantly different than the current library system which had a m = , t( ), p .05 (2-tailed).
