Use 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 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.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
