STAT 203 Study Guide - Midterm Guide: Binomial Distribution, Standard Score, Standard Error
Document Summary
We take a simple random sample of n people from this population and record the n incomes. A study of the health of such children in later years examined a random sample of 219 children. Their mean weight at birth was x =x = 810 grams. This sample mean is an unbiased estimator of the mean weight in the population of all elbw babies. Srs of 100 students and average their sat math scores. The mean brushing time is and the standard deviation is . We will assume the following to be known values for the population. We know that the mean time until death after diagnosis is 6. 5 years. We also know that the standard deviation of time until death is 4. 1 years. Further, we know that the distribution of time until death is very strongly skewed to the right (positively skewed) for this population.
