Last year, during an investigation of the time spent reading e-mails on a daily basis, researchers found that on Monday the average time was 50 minutes. Office workers claim that with the increased spam and junk mail, this time has now increased. To conduct a test, a sample of 25 employees is selected with the following results: sample mean = 51.05 minutes and sample standard deviation = 14.2 minutes. What is the critical value for ? = .05 to test the hypotheses. Assume the time spent reading e-mails is normally distributed. Set up the problem. Calculate the test statistic. State your conclusion. Reject/Fail? Based on your decision about the hypothesis testing what kind error is possible? Type 1 or Type 2

Suppose that Jean studied for the Graduate Management Admission Test (GMAT) using a well-known preparation class and was thrilled to receive a total score of 740. Her friend Eric, however, thinks she would have scored just as well without the class. To test the efficacy of the class, they obtain a small but random sample of 17 test results from other students using the same class. This sample's average is 559.42 with a standard deviation of 108.03. In comparison, the national average was 550.12. Assume the population's results are normally distributed but that its standard deviation is not known. Jean and Eric decide to perform a two-tailed t‑test at a significance level of α = 0.05. How many degrees of freedom should they use in their calculations? df = ___.

Suppose that the distribution of heart rates for medium sized dogs is normally distributed with mean 115 beats per minute and standard deviation 18 beats per minute. Stacy takes her medium sized dog, Scooter to the veterinarian for a wellness check and learns that scooters heart rate is 126 beats per minute. Answer question Ca. What is the standard score for scooters heart rate?= .61b.What percentage of medium-sized dogs have a heart rate that is lower than Scooters? = 76%c. Stacy learns from the veterinarian that dogs with heart rates in the upper 8% may be in danger of heart failure. For medium-sized dogs, a dangerous heart rate would be one above what value?
