Standard Scores

1. Use both the Student ID and Distance to Work variables.
2. List the Student ID at TESU in ascending order of Distance to Work.
3. Calculate the z-scores associated with each student (use the sample standard sample deviation for this calculation).
4. 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.
4. Take a sample of the first seven data points for the variable Distance to Work (unsorted - use the original order in the dataset).
5. Determine the 95% confidence interval. Use the same mean and SD, but change the sample size to 20 and determine the 95% confidence interval.
6. Describe and compare the two intervals.
