A statistician wishes to determine the difference between two population means. A sample of 18 items from Population #1 yields a mean of 205 with a standard deviation of 12. The sample of 15 items from Population #2 yields a mean of 190 with a standard deviation of 10. Assume that the values are normally distributed in each population. How many degrees of freedom are there for this test? a. 18 b. 14 c.15 d. 17
A company decides to investigate the amount of sick leave taken by its employees. A sample of seven employees yields the following numbers of days of sick leave taken in the past year. 1 1 3 0 0 63 Use this information to answer parts a through c. a. Find and interpret the range. The range is 6 days. Choose the correct interpretation of the range below. A. The largest difference between the mean and any other value is equal to the range. B. The number of days separating the fewest and most sick days taken is equal to the range. C. The range represents the average distance of an observation from the mean. D. The range gives the most useful value for measuring the spread of the data.
