Let X ∼ Bin(124, p) with observed x = 78. Then, the 95% confidence interval for p is . To make the length of the 95% confidence interval for p not greater than 0.05, we need the sample size n to be at least . Based on the data, if we want to test H0 : p ≤ 0.6 against Ha : p > 0.6, we conclude at significance level α = 0.05. Let F ∼ F4,7. Assume c1 satisfies...
