Assignment Help Basic Statistics
Reference no: EM132643364

Standard ScoresUse both the Student ID and Distance to Work variables. 

  1. List the Student ID at TESU in ascending order of Distance to Work. 
  2. Calculate the z-scores associated with each student (use the sample standard sample deviation for this calculation).
  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.
