Does cell phone use while driving impair driver reaction times? At the Univ. of Utah the times (in milliseconds) of 32 drivers using cell phones to depress the brake pedal were compared to the reaction times of 32 drivers who were listening to the radio. For the cell phone users the results were = 585.2, s = 89.6; for the radio listeners the results were = 533.7, s = 65.3. Determine a 95% confidence interval for μ-μ where μ is the mean reaction for drivers using cell phones. Use df = 57.
