A smartphone manufacturer wants to construct a 95% confidence interval for the difference between the mean of performance of two kinds of batteries (two groups). Independent random samples are considered from groups 1 and 2 of batteries and the time measured in hours that the batteries will last on a full charge is recorded. Dataset is available at batteries performance.csv Assuming the measurements for both groups follow a normal distribution and the populations' variances are not equal, what is the lower bound of a 95% confidence interval for the difference between the means of the first group and the second group. i.e., ₁ - M₂. Note: Please round your answer to four decimal places.
