Question 1

A random sample of n observations, selected from a normal population, is used to test the null hypothesis H0: σ2 = 155. Specify the appropriate rejection region.
Ha: σ2 < 155, n = 14, α = .01
◦ χ2 < 27.6883
◦ χ2 < 29.1413
◦ χ2 < 4.66043
◦ χ2 < 4.10691

Question 2

A random sample of n observations, selected from a normal population, is used to test the null hypothesis H0: σ2 = 155. Specify the appropriate rejection region.
Ha: σ2 ≠ 155, n = 10, α = .05
◦ χ2 < 3.32511 or χ2 > 16.9190
◦ χ2 < 3.24697 or χ2 > 20.4831
◦ 2.70039 < χ2 < 19.0228
◦ χ2 < 2.70039 or χ2 > 19.0228

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
