t test or the Z test. Yuwen applied the t-test to the data and concluded that the null hypothesis cannot be rejected. Great job picking the test and applying it!
Below is the reasoning for choosing t-test or the z-test I follow the chart presented in the lecture slides. The following is the path
Do samples come from same or different populations
Assume the data is parametric
Number of categories is 2
Data is not paired
if we assume variance is same, then we use Z-test else we use Welch t test.
Perform the appropriate statistical test.
figures show the results.

Conclusions

- The result and its significance, including the weaknesses and strengths of the analysis.
