We see that this answer agrees with the result of Example 2.
Besides doing these calculations manually, you can also use the TI83 calculator. Example 2 will be done using both
methods and the TI83.
Step One:
Step Two:
Notice the sum of the data(∑x) = 300
Notice the number of data(n= 12 )
Notice the mean of the data(x ̄= 25 )
Example 2 was done using the TI83 calculator by using List One only. Now we will do Example 2 again but this
time we will utilize the TI83 as a frequency table.
Step One:
