Answer #1

Answer :

      Eastimating the population variance = (Sum of square deviation) (M -1)

      So option C is correct

                  ( dividing the sum of squared deviations by N-1 instead of N )

A random sample n=30 is obtained from a population with unknown variance. The sample variance s2 = 100 and the sample mean is computed to be 85. Test the hypothesis at α = 0.05 that the population mean equals 80 against the alternative that it is more than 80. The null hypothesis Ho: µ = 80 versus the alternative H1: Ho: µ > 80. Calculate the test statistic from your sample mean. Then calculate the p-value for this test using...

Using a random sample of size 77 from a normal population with variance of 1 but unknown mean, we wish to test the null hypothesis that H0: μ ≥ 1 against the alternative that Ha: μ <1. Choose a test statistic. Identify a non-crappy rejection region such that size of the test (α) is 5%. If π(-1,000) ≈ 0, then the rejection region is crappy. Find π(0).
