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
Which of the following shows how to compute the mean? A. mean
=
(sum of all values)
\times
(total number of values) B. mean
=( total number of values )/( sum of all values )
C. mean
=
sum of all values + total number of values D. mean
=( sum of all values )/( total number of values )
The sum of all values is
◻
(Type an integer or a decimal.) The total number of values is
◻
(Type a whole number.) Calculate the mean. The mean is
◻
(Round to one decimal place as needed.) 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 halfway between the
◻
h and
◻
th values in the sorted data set. (Type whole numbers. Use ascending order.) B. The median is the
◻
th value in the sorted data set. (Type a whole number.) Thus, the median is (Type an integer or a decimal.) The mean is (1)
◻
the median. (1) equal to
◻
less than
