Use technology to help you test the claim about the population mean, u, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: us 1260; a = 0.04; o = 196.49. Sample statistics: x = 1285.94, n 250 Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: H2 1285.94 O B.
