Define H0 : μ = 30 and H1 : μ > 30. What is the probability of observing a sample mean X = 33 or larger if H0 is true?
Statistical Methods for Psychology 1. Suppose we are sampling from a population that is known to be normal with standard deviation σ = 10. However, the mean μ is unknown, so we’ll have to estimate it. (a) A sample of N = 9 is drawn and is found to have mean X = 25. Compute […]
