ISYE-6644 Simulation UPDATED Actual Questions and CORRECT Answers (8.3) Find the sample variance of -3, -2, -1, 0, 1, 2, 3 - CORRECT ANSWER- 14/3 (or 4.666). If sample is entire population than variance is 4. (8.1) M/M/1 queue - CORRECT ANSWER- queue length having a single server. (8.3) If the expected value of your estimator equals the parameter that you're trying to estimate, then your estimator is unbiased. True of False - CORRECT ANSWER- True

(8.3) Find the sample variance of -3, -2, -1, 0, 1, 2, 3 - 14/3 (or 4.666). If sample is entire population than variance is 4. (8.1) M/M/1 queue - queue length having a single server. (8.3) If the expected value of your estimator equals the parameter that you're trying to estimate, then your estimator is unbiased. True of False - True. This is the definition of unbiasedness (8.3) If X1, X2, ..., Xn are i.i.d. with mean mu, then the sample mean X-bar is unbiased for mu. True or False ...

Suppose a political party wants to estimate how favorable a certain candidate is to state voters. To do so, a sample of 400 registered voters were selected. Suppose 160 found the candidate "favorable". An estimate of the proportion of the population of registered voters is 160/400=40%. This is an example of what? Example of finite sample Suppose a new tire is being developed and the manufacturer wants to know the useful life of the new type of tire. A sample of 120 tires were tested an...
