mean waiting time, which of the following is true? The standard deviation of the sampling distribution for x will be proportionally larger than the population standard deviation, depending on the size of the sample. The sampling distribution will be left-skewed. Provided that the sample size is sufficiently large, the sampling distribution for will be approximately normal with a mean equal to the population mean that they wish to estimate. C The sampling distribution will also be right skewed for large sample sizes.
