Question

USH Financial is examining the use of its midtown ATM machine. The numbers of transactions made per day at this ATM during the past 7 days are as follows: 74,66,72,56,79,98,84 what is the mean,median and mode

Answer 1

The data set is given as follows;

`\begin{gathered} 74,66,72,56,79,98,84 \\ (1)\text{The mean is given as} \\ M=(\Sigma x)/(x) \\ M=(74+66+72+56+79+98+84)/(7) \\ M=(529)/(7) \\ M=75.57 \\ (2)To\text{ calculate the median, you arrange the numbers in ascending order} \\ \text{That is from least to greatest, the numbers are;} \\ 56,66,72,74,79,84,98 \\ \text{Counting 3 numbers from both left and right, the middle value is 74} \\ (3)\text{The mode is the value that occurs most frequently.} \\ \text{From the data set, all values occur only once, hence there is no mode in this data set} \end{gathered}`

Therefore the answers are;

(1) Mean = 75.57

(2) Median = 74

(3) Mode = No modal value
