2. The length-of-stay [LOS] for dogs at the Air Bud er Bed (AB& B) has averaged 9 days. Due to a recent economic crisis, the firm's CEO believes the mean LOS at the AB&B has decreased significantly. To test the CEO's belief, you examine records for a random sample of 41 dogs that recently stayed at the AB&B. The sample data reveal an average LOS of 8.38 days, with a standard deviation of 2.154 days. Test the CEO's belief at the 0.05 level of significance. 2) State the null and alternative hypotheses associated with the test. (0.5 point) b) What is the calculated value of the associated test statistic? (0.25 point) C) What is the critical value of the associated test statistic? (0.25 point) d) State your decision about the null hypothesis by comparing the calculated and critical values of the test statistic (Parts b and c). (0.25 point) e) What is the p-value of the associated test statistic? State your decision about the null hypothesis by comparing the p-value and the level of significance. (0.5 point) f) State your conclusion (meaning, describe what the decision means here). (0.5 pt)
