Statistical significance would mean that the researcher carried out the appropriate statistical tests to confirm that the difference between the two age groups was unlikely to be a result of chance.
Likely, a researcher would want the p value (probability value) to be less than 0.05, which means there is only a 5% chance that these observations are random.
The test a researcher would likely perform to test statistical significance on this data is an unpaired t test, which compares the averages of two independent groups to see whether there is a significant difference between them.
