A market analyst conducted a Chi-square test of independence to investigate whether there is a significant association between a customer's age category (under 30 vs. 30 and over) and their preferred payment method (digital wallet vs. physical card).
After analyzing the transaction data, the calculated value of Chi-square was found to be χ2=2.15\chi^2 = 2.15χ2=2.15. The critical value table for df=1df = 1df=1 indicates that the critical value at the p≤0.05 p \le 0.05\,p≤0.05 significance level is 3.84.
Based on these values, what conclusions can be drawn from this statistical analysis?
