Use technology to help you test the claim about the population mean, u, at the given level of signicance, or, using the given sample statistics. Assume the population is normally distributed. Claim: p > 1270; or = 0.08; o = 197.75. Sample statistics: 32:12:39.45. n = 275 E) Identify the null and altemative hypotheses. Choose the correct answer below. 0 A. : p s 1270 8. : 21289.45 ll :u>1270 :p1270 tu 1289.45 Ha: pl) 1289.45 : u $1289.45 Calculate the standardized test statistic, z. Use the z formula. The standardized test statistic. z is D. (Round to two decimal places as needed.) Determine the P-value. Hint: Keep in mind that P-value depends on the type of test
