That is, we want to test the null hypothesis H0 : [31 = 0 against the alternative hypothesis Ha : l 76 0. What is the distribution of the test statistic for this test? Previous page Jump to...

For the test, how many degrees of freedom does the distribution of the test statistic, x, have? O df= 1 O df = 4 O df= 3 O df = 2 b. What is the value of the observed test statistic associated with the test? O x2 = 6.251 O x 2 = 7.089 O x 2 = 6.924 O x 2 = 3.423 c. What is the p-value associated with the test? O p-value = 0.009 O p-value = 0.12 O p-value = 0.008 O p-value = 0.05 d. At the 5% level of significance, does the p-value support the claim that there is an association between the presence of antibody to milk protein and survival after a heart attack? Explain. No, since the p-value = 0.009 0.05. O No, since thepvalue = 0.09 > 0.05. 0 Yes, since thepvalue = 0.009
