.A sample of 9 measurements, randomly selected from a normally distributed population,
resulted in x= 2.6, and s= 0.9 Conduct a hypothesis test to verify the claim that the
population mean is greater than 2.5 . Use a=.05
Method A: M1= 54, SS1= 400, n1= 15
Method B: M2=40, SS2= 440, n2=15
Using alpha=0.05 should the null hypothesis by rejected for the above data?
A random sample of a size n = 25 is obtained from a population with a variance of σ2 = 400, and the sample mean is computed to be x̅ c = 70. Consider the null hypothesis H0: μ = 80 versus the alternative hypothesis H1: μ = 80. Compute the p-value for this test
