p-value significance

The following is a solution to a practice question I have just attempted.

p-value = 0.0237.

Method A performs a one-tailed test. The result is significant at the 1% but not the 5% level. Some evidence that the yoga group have a lower mean age.

------------

Is it just me, or are the significance levels mixed up? For example I would of thought the following is correct:

0.0237 < 0.05, therefore significant at 5%
0.0237 > 0.01, therefore NOT significant at 1%
