Body armor provides critical protection for law enforcement personnel, but it does affect balance and mobility. The article "Impact of Police Body Armour and Equipment on Mobility" (Applied Ergonomics, 2013: 957–961) reported that for a sample of 52 male enforcement officers who underwent an acceleration task that simulated exiting a vehicle while wearing armor, the sample mean was 1.95 sec, and the sample standard deviation was .20 sec.
Does it appear that true average task time is less than 2 sec? Carry out a test of appropriate hypotheses using a significance level of .01.
