... distance from the value to the mean. From these two examples, I can see that 0 lies the greater distance above the mean and 8.8 lies the greatest distance below the mean. 9. A. The mean is adding up all 25 beta numbers and then divide by 25 ( 26.813)/25 = 1.073). The variance is the sum of each data ...

1 Reminder of Definitions 2 Unknown Population Standard
... Throughout we assume that the sample size n is at most 5% of the population size N . This allows us to ignore the finite population correction factor when talking about the standard deviation of the sample mean. When the population standard deviation σ is not known, it can be √ approximated by the s ...

7. Point Estimation and Confidence Intervals for Means
... The 1.96 value comes from the z table. If you look in the z table, you will see that the value that corresponds to 1.96 for z is .025. What this means is that if we go 1.96 units from the mean, there will be .025 of the distribution (or 2.5% of the distribution) at either tail of the distribution. I ...
