Explanation:
Detailed explanation-1: -In a test of H0: µ = 100 against Ha: µ ≠ 100, a sample of size 10 produces a sample mean of 103 and a P-value of 0.08. Which of the following is true at the 0.05 level of significance? There is sufficient evidence to conclude that µ ≠ 100. There is sufficient evidence to conclude that µ = 100.
Detailed explanation-2: -A test’s power can be increased in two ways: by increasing the sample size or by raising the significance level. As a result, increasing the power of a significance test with the help of the sigma’s significance level.
