Use technology and a t-test to test the claim about the population mean μ at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: μ> 80; x = 0.01 Sample statistics: x=83.2, s = 3.5, n = 29 What are the null and alternative hypotheses? Choose the correct answer below. O A. Ho: μ = 80 HA: μ#80 O C. Ho: μ#80 HA: μ = 80 What is the value of the standardized test statistic? The standardized test statistic is 4.92. (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value = (Round to three decimal places as needed.) B. Ho: μ≤80 HA: μ> 80 D. Ho: μ ≥80 HAH<80
