A company wants to estimate, at a 95% confidence level, the annual difference between male employees' average tardiness for work and female employees' average tardiness. For this, he randomly drew 12 from men and 10 from women. It was found that male employees' average annual tardiness time for work was 12 minutes and variance was 2 minutes, and female employees' average annual tardiness time to work was 10 minutes and variance was 3 minutes. Assuming that the population variances from which the samples are drawn are homogeneous, which of the following is the confidence interval estimate for the difference between these two population means?
