2 independent sample Hypothesis T test for mean and CIs

In the Visualizer, copy and paste the first example data set (starts with 81.39) and the second (starts with 196.54).
Does each look normalish?:
Do they look like they are from 1 or from 2 populations:

Paste the data or their statatistics into the 2-Samp T-Test / 2 Samp T-Int webpage.
H₀:μ₁=μ₂ H_a:μ₁≠μ₂ "H_a ≠ H₀" Two-tailed.

t crit α=.05 crit α=.01 p value Reject H₀? CL E CI [ CI ] has 0? Reject H₀?
