Step 1 of 5) Police Dispatch Officer Thompson of the Bay Ridge Police Department works the graveyard shift. He averages 4.5 calls per shift from his dispatcher. Assume the number of calls follows a Poisson distribution. Would it be unusual for Officer Thompson to get fewer than 2 calls in a shift 4UFQ Professor Neill wants to know if the reaction time in the dominant hand is less than the reaction time in the nondominant hand. We express this as md 6 0. We have H0: md = 0 second versus H1: md 6 0 second This test is left-tailed. 4UFQ The level of significance is a = 0.05. Classical Approach 4UFQ The sample mean is d = -0.0132 second and the sample standard deviation is sd = 0.0164 second. The test statistic is t0 = d0 sd 1n = -0.0132 0.0164 112 = -2.788 Because this is a left-tailed test,
