Use the shared results from the Student Data Table to complete the following questions. Standard ScoresUse 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/SamplesTake 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.
