Suppose our alternative hypothesis is um 7Hw- Find the P-value and use it to decide whether there is evidence at level of significance 0.05 that women with unpaid credit card debt have a different level of debt than men (of the same education level, marital status, and age) with unpaid credit card debt. Clearly explain how you decided. O A. There is evidence at level of significance 0.05 that women have a different level of debt than men B. There is not evidence at level of significance 0.05 that women have a different level of debt than men

We want to see if Taiwanese women with unpaid credit card debt have similar card balances as Taiwanese men with unpaid credit card debt. In a matched pair study of credit card debt, 181 women were paired with 181 men with the same education level, the same marital status,and the same age. Our null hypothesis is that the average debts are the same: w=Pm: We letd= debtm-debt, for each matched pair. We find d = 10992- and s, =39341 (in Taiwanese dollars). The degrees of freedom is The value of the test statistic TS =d/(s,//n) is
