Use a t-test to test the claim about the population mean w at the given level of significance a using the given sample statistics. Assume the population is normally distributed Claim y 2 8200, a = 0.10 Sample statistics: x=7900, $ = 440, n=23 What are the nuit and alternative hypotheses? O A. Hop*6200 H = 8200 OC. Hor=8200 H#8200 OB. Ho 128200 H, με 8200 OD. Hy58200 H>8200 What is the value of the standardized test statistic? The standardized test statistici (Round to two decimal places as needed.) What is the P-value? Pa (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O A Reject Ho.
