T-scores are used to account for the absence of population standard deviation or a small sample size.
x-bar is the sample mean.
ยต is the population mean.
s is the sample standard deviation.
n is the sample size.
We find the p-value range associated with the t-score in this table.
t-score = 1.535
df = 34
0.05 < p-value < 0.10
This means that 5 - 10% of the distribution occurs to the right of our t-score!
