A random sample of n = 45 observations from a quantitative population produced a mean x = 2.8 and a standard deviation s = 0.29. Your research objective is to show that the population mean μ exceeds 2.7. Calculate β = P(accept H0 when μ = 2.8). (Use a 5% significance level. Round your answer to four decimal places.) β =
