What's the best way to solve these?

+ Pts Find the critical value for a sample with n = 12 and a = 0.01 if Ha: H > 504. Round your answer to the thousandths place (3 decimal places). (Note: Assume the population is normal and the population standard deviation is unknown.) D Question 12 4 pts You wish to test the claim that u = 47 at a level of significance of a = 0.05 and are given sample statistics n = 14, x = 54, and s = 15. Compute the value of the standardized test statistic, t. Round your answers to three decimal places
