Question content area top Part 1 Find the mean and median for the waiting times at Big Bank given below. Show your work clearly, and verify that both are the same. The following values are measured in minutes. Big Bank (three lines): 4.1 5.2 5.6 6.2 6.7 7.2 7.7 7.7 8.5 9.3 11.0 Question content area bottom Part 1 Which of the following shows how to compute the mean? A. mean=(sum of all values) × (total number of values) B. mean=sum of all values+total number of values C. mean=sum of all valuestotal number of values Your answer is correct. D. mean=total number of valuessum of all values Part 2 The sum of all values is 79.2 79.2. (Type an integer or a decimal.) Part 3 The total number of values is 11 11. (Type a whole number.) Part 4 Calculate the mean. The mean is 7.2 7.2. (Round to one decimal place as needed.) Part 5 Notice that the data are given in ascending order. How should the median be found in this case? Select the correct choice below and fill in the answer box(es) to complete your choice. A. The median is the 6 6th value in the sorted data set. (Type a whole number.) Your answer is correct. B. The median is halfway between the enter your response here th and enter your response here th values in the sorted data set. (Type whole numbers. Use ascending order.)
Part 6 Thus, the median is 7.2 7.2. (Type an integer or a decimal.) Part 7 The mean is equal to the median.
