WebThe correlation is -0.650. The sample size is 7, so there are 5 degrees of freedom. After substituting into the test statistic, t = − 0.650 7 − 2 1 − ( − 0.650) 2, the value of the test statistic is -1.91. Based on the t-table with 5 degrees of freedom, the two-sided p-value is greater than 0.10 (actual 0.1140). WebΧ 2 = 8.41 + 8.67 + 11.6 + 5.4 = 34.08. Step 3: Find the critical chi-square value.
