Problem- In a fictitious lab experiment a class studied two acid base reactions and recorded the temperature change. class averages were reported

1) 30 ml of 3 molar hcl with 30 ml of 1.5 naoh change in temp was 12.2 +or - 1.3 degrees C

2) 30 ml of 1.5 molar hcl with 30 ml of 3 molar naoh changes in temp was 13.7+or- 1.7 degrees c

Can we conclude from these data that delta T1 and delta T2 are significantly different?

How do I yet start setting this up? Thank you
