Standard Scores:

Use both the Student ID and Distance to Work variables.
List the Student ID at TESU in ascending order of Distance to Work.
Calculate the z-scores associated with each student (use the sample standard deviation for this calculation).
Identify potential outliers and explain your reasoning.

Confidence Intervals/Samples:

Take a sample of the first four data points for the variable Distance to Work (unsorted - use the original order in the dataset).
Determine the 95% and 99% confidence intervals using the same size of 4.
Describe and compare the two intervals.

Take a sample of the first seven data points for the variable Distance to Work (unsorted - use the original order in the dataset).
Determine the 95% confidence interval. Use the same mean and SD, but change the sample size to 20 and determine the 95% confidence interval.
Describe and compare the two intervals.
