A. Write TRUE t'fthe statement is true, and FALSE if otherwise. (10 points) 1. The mean ol'the sample means is equal to the mean of the sample distribution. 2. As the sample it becomes larger, the sampling distribution of the sample means tend to approximate normal probability distribution. 3. If the variance is 12, then the standard deviation is 144. 4. When the sample size n is 30, and the standard deviation of the population is unknown, then we can use the standard deviation of that sample. 5. When the z score is negative, then the mean it is less than the population mean
