Question

Use technology to help you test the claim about the population mean, mu, at the given level of significance, alpha, using the given sample statistics. Assume the population is normally distributed claim mu > 1210; alpha = 0.02 sigma = 204.68. Sample statistics: x bar = 1225.56, n=250 Identify the null and alternative hypotheses. Choose the correct answer below. A. H_0: mu lessthanorequalto 1225.56 B. H_0: mu > 1225.56 H_0: mu greaterthanorequalto 1225.56 H_0: mu 1225.56 H_a: mu lessthanorequalto 1225.56 D. H_0: mu greaterthanorequalto 1210 H_a: mu 1210 F. H_0: mu > 1210 H_a: mu lessthanorequalto 1210

Explanation / Answer

Population is normally distributed and we need to decide Null And Alternative hypothesis with given conditions. Here we are testing population mean which is greater than 1210. So our first assumption would be it is greater than 1210. Then our next claim in this case that the mean value is either small or equal to 1210. Hope this will help you to find the answer.
