a.Using the Jarque-Bera test, specify the null and alternative hypotheses to determine whether or not the data are normally distributed.   H₀: S = 0 and K = 0; H_A: S ≠ 0 and K ≠ 0H₀: S = 0 and K = 0; H_A: S < 0 and K < 0H₀: S = 0 and K = 0; H_A: S > 0 and K > 0

b.At the 1% significance level, what is the critical value? (Round your answer to 3 decimal places.)

  Critical value  

c.Calculate the value of the test statistic. (Round intermediate calculations to 4 decimal places and final answer to 2 decimal places.)

  Test statistic  

d.What is the conclusion?   Reject H₀; there is enough evidence to support the claim that the data are not normally distributed.Do not reject H₀; there is not enough evidence to support the claim that the data are not normally distributed.Reject H₀; there is not enough evidence to support the claim that the data are not normally distributed.Do not reject H₀; there is enough evidence to support the claim that the data are not normally distributed.
