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: u > 1270; 1289.45 Ha: us 1289.45 Calculate the standardized test statistic, z. Use the z formula. The standardized test statistic, z is (Round to two decimal places as needed.) Determine the P-value. Hint: Keep in mind that P-value depends on the type of test. Left-tailed test: P-value=Area (where Area = the number from the tekla) Right-tailed test: P-value=1-Area Two-tailed test: P-value=2*Area P= (Round to three decimal places as needed.) reject Compare P with a and then State your conclusion. degree support Determine the outcome and conclusion of the test. Ho. At the 8% significance level, there enough evidence to the claim. Time Remaining: 00:57:47 Next
