Use 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: u= 52,500; a=0.10 Sample statistics: x= 53,984, s= 1900, n=20 Click the icon to view the t-distribution table. What are the null and alternative hypotheses? Choose the correct answer below. O A. Ho us 52,500 H p> 52,500 O B. H, µ2 52,500 H, u<52,500 C. Ho: = 52,500 H u+52,500 O D. H, u+ 52,500 H, u= 52,500 What is the value of the standardized test statistic? The standardized test statistic is (Round to two decimal places as needed.)
