Dr. Gupta is running a rabies vaccination clinic for dogs at the local grade school. He can "shoot" a dog every 3 minutes. It is estimated that the dog will arrive independently and randomly throughout the day at a rate of one dog every 6 minutes, according to a Poisson distribution. Also assume that the Dr. Gupta’s shooting times are negatively exponentially distributed. Answer (a) to (f). Avg. service rate µ = Avg. arrival rate λ =

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
