t-tests are usually sum statistical tests carried out to check the relationship between variables and the validity of an experiment...now in u6 xmz...usually, theyl giv u the value of the experimental t-value, and a table comprsing of t-values for the experiment. all u hav 2 do is check d value of t correspondin to 0.05 value. if ur t-valu z greater or equal to this value...dat means dat u hav a 95% confidence that the experimental t-value is significant. and the null hypothesis is rejected! so then u can accept da relationship shwn by the experimnt.
