incorrect. 1. The mean of the sampling distribution of the means is less than the population mean. 2. Standard error is always non-negative. 3. The sample size of 45 will give a smaller standard error of the mean than a sample size of 35. 4. A standard deviation of 1.45 is a good estimate of the mean than a standard deviation of 0.75. 5. Random samples of 10 are drawn from a population with u = 90 and o = 15. The population mean is 10.
