Unformatted text preview: 200 would be greater than this. (f) Greater than 0.65. The power against the alternative p 4 is 0.691332, and the alternative p 3 is farther from the null than p 4. So the power against the alternative p 3 is greater than 0.691332. (g) It’s impossible to tell from the output. The power against the alternative p 45 will be less than the power against p 4, which is 0.691332. But we cannot tell without calculating whether the power will be less than 0.65. 11. (a) Two-tailed. The alternate hypothesis is of the form μ 1 μ 2 ∆ . (b) Less than 0.9. The sample size of 60 is the smallest that will produce power greater than or equal to the target power of 0.9....
