1. The Hypothesized mean is the difference between the two means you are comparing.
2. t-stat is the calculated t value for the difference shown in number one.
3. P-values for 1 and 2 tail indicates what the alpha level actually calculated from the t-stat in number 2. The one tail is 0.43 and two tail is 0.86. Depending on what you alpha level is set at (usually 0.05 or 0.01) both of these tests indicate that there is not a statistically significant difference in the means. That p-values would need to be less than 0.05 or 0.01 depending on your alpha level.
