Human: With regards to the use of a t-test data analysis, how do I know if the t-test is appropriate for? Assistant: 
You should check if you have a normal distribution. If not, the t-test is inappropriate. If you do have a normal distribution, you should use the t-test to determine if the mean difference between two samples is statistically significant. If the p-value is less than 0.05, then you can conclude that the difference is statistically significant.
