Document Summary
Chapter 7: sampling distributions: sampling distributions describe the distribution of statistics, parameters. b, both parameters and statistics, neither parameters nor statistics. If the expectation of a sampling distribution is located at the parameter it is estimating, then we call that statistic: unbiased, minimum variance, biased. d) random. 173 sampling distributions: for air travelers, one of the biggest complaints involves the waiting time between when the airplane taxis away from the terminal until the flight takes off. This waiting time is known to have a skewed-right distribution with a mean of 10 minutes and a standard deviation of 8 minutes. Sampling distributions 174: true or false: the amount of time it takes to complete an examination has a skewed-left distribution with a mean of 65 minutes and a standard deviation of 8 minutes. If 64 students were randomly sampled, the probability that the sample mean of the sampled students exceeds 71 minutes is approximately 0.
