This function calculates a t-test between
the pm25_A, pm25_B. A t-statistic and a p-value will be
returned for each day. All returned values are expected to hover near 0 for a
properly functioning sensor. The t-statistic and p-value serve to test whether
or not the pm25_A and pm25_B data are significantly different
based on a student<U+2019>s t-test.
