Hi, I need help. Thanks

X" = E (obs-exp)z Expected Frequencies = Row Total x Column Total exp Grand Total degrees of freedom = (# rows - 1) x (# columns - 1) A 2016 Stats Canada study looked at the percentage of Canadian families that are debt-free by age group. The results of the random sample of 2,000 Canadian families is summarized in the table below. Is there enough evidence to conclude that being debt-free depends on age? Test the hypothesis at the 5% level of significance. Age (in years) Debt Free? | Under 35 35 to 44 45 to 54 55 to 64 65 and older | Total Yes 140 60 48 77 275 600 No 460 340 202 198 200 1.400 Total 500 400 250 275 475 2,000 Ho HA [2] Critical Value [2] Write the expected frequencies in the table [3] Test Statistic [3] Decision/Justify [1] Conclusion: Circle the Correct One [1 mark] A. Yes, there is enough evidence to conclude that being debt-free depends on age. B. No, there is not enough evidence to conclude that being debt-free depends on age
