I am in a data driven decsion making class. Part of the process is creating a spreadsheet in excel. In my task I used a t test sample . My results are as follows.

t-Test: Two-Sample Assuming Unequal Variances Time To Fill - in days Average time to fill

Mean 35.13333333 45

Variance 974.6712644 0

Observations 30 30

Hypothesized Mean Difference 0

df 29

t Stat -1.731019669

P(T<=t) one-tail 0.047038333

t Critical one-tail 1.699127027

P(T<=t) two-tail 0.094076667

t Critical two-tail 2.045229642

What I am trying to figure out is if I should reject the null hypothesis or the Alternative Hypothesis. Can you please break down my findings so I can understand.
