Chapter 8
Each group got assigned a set of data. Brandon, Dallas, and I got assigned with adult IQ scores. We had to figure out the sample size, sample mean,standard deviation, degrees of freedom, critical values, maximal margin or error, and determine the confidence interval. We found out that with a 90% confidence that the mean IQ is greater than 117.78, and less than 118.18. We were then able to say with a 95% confidence that the mean IQ score is greater than 111.18, and less then 118.78. Finally we found that 99% confidence that the mean IQ score is greater than 109.86, and less than 120.1.
