If these are my results from my t-test:

t-test results:

degrees of freedom: 194

hypothesized mean difference: 0

pooled variance: 46.52

Test Statistics: 1.099

One tailed distribution:
p-level: .13643; Critical value (10%): 1.28593

According to t-table my tscore is 1.286

So, fail to reject the null since t score (1.286) is greater than critical value (1.28593)? What do I do if the values are so similar?
