A reading specialist suspects that there is a difference in the average reading speed between senior boys and senior girls at her high school. To test her claim, random samples of 25 senior boys and 25 senior girls were selected. The reading speed of each student was measured. The reading specialist uses the data obtained to test the hypotheses H0: μboys - μgirls = 0 versus Ha: μboys - μgirls ≠ 0, where μboys and μgirls are the true mean reading speed of all senior boys and girls at her high school.
