Given the following information about two random samples selected from two populations which option correctly describes the shape, mean, and standard deviation of the sampling distribution of Hã, – Hāz? Population Population Population Shape Population Mean Standard Deviation Sample Size Sample Mea Population 1 Approximately Normal 5.8 0.8 38 6.2 Population 2 Approximately Normal 12.3 1.9 42 11.9 None of these is correct. The shape is approximately normal and Hãn - Hãz = 6. 5. The shape, mean, and standard deviation are all unknown. The shape is approximately normal and µz, – Hãz = -5. 7. The shape is approximately normal and HE, – Hī, = -6. 5.

Given the following information about two random samples selected from two populations which option correctly describes the shape, mean, and standard deviation of the sampling distribution of H, – Hūz? Population Population Population Shape Population Mean Sample Size Sample Mean Standard Deviation Population 1 Approximately Normal 5.8 0.8 38 6.2 Population 2 Approximately Normal 12.3 1.9 42 11.9 None of these is correct. The shape is approximately normal and Mãn – Hữ, = 6. 5. The shape, mean, and standard deviation are all unknown. The shape is approximately normal and Hã, – Hãz = -5.7. The shape is approximately normal and H, – Hã, = -6. 5. The shape is approximately normal and H, – Hã, = 5. 7. -

A random sample of size n1 = 50 is selected from a large population with an unknown shape. A second random sample of size n2 = 25 is selected from a different large population with an unknown shape. Which of the following is a correct statement about the conditions for constructing a confidence interval for Hi – H2? The Random condition is met for each sample and the Normal/Large Sample condition is also met for each sample. The Random condition is met for each sample, but the Normal/Large Sample condition is not met for at least one sample. The Random condition is not met for each sample, but the Normal/Large Sample condition is met for each sample. Neither the Random condition nor the Large Counts condition for each sample is met.
