3. Identify potential outliers and explain your reasoning.
Confidence Intervals/Samples
1. Take a sample of the first four data points for the variable Distance to Work (unsorted - use the original order in the dataset).
2. Determine the 95% and 99% confidence intervals using the same size of 4.
3. Describe and compare the two intervals.
1. Take a sample of the first seven data points for the variable Distance to Work (unsorted - use the original order in the dataset).
2. Determine the 95% confidence interval. Use the same mean and SD, but change the sample size to 20 and determine the 95% confidence interval.
3. Describe and compare the two intervals.
