An environmental psychologist investigates whether there is an association between a resident's primary commute mode (Train, Bus, or Bicycle) and their self-reported commuting stress category (High vs Low).

The calculated value of chi-square ( $χ2\chi^2$ ) is 6.425. For this study, the degrees of freedom ( $df$ ) = 2.

Write the significance statement at the 5% level of probability for this study, using the table of critical values below.
