46 of 50 Why is the mean of a distribution of sample means said to be "expected" to equal the population mean? We need to allow for rounding error. It is likely to vary somewhat from the actual population mean due to sampling error as a result of random variation in the sample data. It is likely to vary somewhat from the actual population mean due to procedural errors in the sampling process. The samples may not be large enough to accurately reflect the population data. 47 of 50 The probability of an event is described as P(1 < x < 2). What type of random variable are we concerned with? discrete continuous either discrete or continuous neither discrete nor continuous 48 of 50 The average ticket price for a Spring Training baseball game is $31.97, with a standard deviation of $7.96.
