Write true if the statement is correct, otherwise false. _____1. A good estimator should be biased. _____2. The larger the sample size, the closer the point estimate is to the true parameter. _____3. Interval estimate describe a range of values used to estimate a population in using a predetermined degree of confidence. _____4. Central Limit Theorem states that if you have a population mean and standard deviation and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. _____5. Statistics is the measure stained using the data in a sample. _____6. The distribution of the sample means when samples of the same size are selected from a population and the means are computed. _____7. Using higher confidence levels means decreasing the range of the confidence interval. _____8. The sample distribution of sample mean obtained from repeated samples of the size drawn from the sample population. _____9. The smaller the sample size, the better the approximation of the normal distribution is. _____10. A samples size is considered large if it is more than 30.
