Question: A random sample of n = 45 observations from a quantitative population produced a mean x = 2.6 and a standard deviation s = 0.25.

A random sample of n = 45 observations from a quantitative population produced a mean x = 2.6 and a standard deviation s = 0.25. Your research objective is to show that the population mean , exceeds 2.5. (Use a 5% significance level. Round your answers to four decimal places.) LOL USE SALT Calculate S = P(accept Ho when # = 2.5). 8 = Calculate S = P(accept Ho when # = 2.7). Calculate # = P(accept Ho when u = 2.8). You may need to use the appropriate appendix table to answer this question. Need Help
