1 pts Assume a simple random sample is used to gather data from a positively skewed population distribution. Then, as you collect more data (i.e., as n increases), which of the following is true? O You expect a histogram of the sampling distribution to be positively skewed. You expect a histogram of the data distribution to ore and more like a normal distribution. The sample mean tends to get farther away from the population mean. By the central limit theorem, the sampling distribution tends to take on more of a bell shape.
