**Waiting Times in a Bank: Comparing Single and Individual Lines****Context:**This exercise involves analyzing the waiting times (in minutes) of customers in two different banking scenarios. In the first scenario, all customers enter a single waiting line. In the second scenario, customers wait in individual lines at three different teller windows. The waiting times for each scenario are provided below. Your task is to calculate the mean and median for each dataset and then compare the results.**Data:**- **Single Line:** 6.4, 6.6, 6.7, 6.8, 7.1, 7.2, 7.6, 7.8, 7.8, 7.8- **Individual Lines:** 4.3, 5.5, 5.8, 6.3, 6.5, 7.8, 8.7, 9.2, 9.9**Instructions:**1. **Calculate the Mean and Median:** - **Mean Waiting Time for Single Line:** [Fill in the blank] - **Median Waiting Time for Single Line:** [Fill in the blank] - **Mean Waiting Time for Individual Lines:** [Fill in the blank] - **Median Waiting Time for Individual Lines:** [Fill in the blank]2. **Compare the Data Sets:** - Determine whether there is a difference between the two data sets that is not apparent from a comparison of the measures of center. If so, what is it? **Options:** - A. The times for customers in a single line are much more varied than the times for customers in individual lines. - B. The times for customers in individual lines are much more varied than the times for customers in a single line. - C. There is no difference between the two data sets.**Your Analysis:**Consider the measures of center and spread to evaluate the differences between the two scenarios. This exercise helps in understanding statistical comparisons in real-life situations.

A rectangle is a four-sided figure that has two sets of parallel sides, so that we have two sides of one length and two sides of another length; a square is just a special case of a rectangle in which all four sides are the same length. Therefore, the procedure for calculating area is the same no matter whether we are dealing with a rectangle or a square. The area of a rectangle is calculated as follows: Area = base x height = b × h In this formula, the base is the width of the rectangle and the height is simply how tall the rectangle Is. For example, if we have a rectangle that is 20 centimeters wide and 10 centimeters tall, its area can be calculated as follows: Area = 20 cm x 10 cm = 200 cm² Note the superscript '2' In our answer; this is because we have multiplied centimeters by centimeters. In economics, we are more likely to be dealing with quantities bought or sold and prices, so don't worry about it too much for our discussion. The area of a triangle A triangle is really just a…
