For a project, the teacher asked a group of seven students to each count the number of pedestrians that cross the street where they live on a certain day. The data collected had a range of 41. Six of the seven data values are shown below. Find the missing data value.
30 comma
19 comma
22 comma
12 comma
32 comma
19
The range of the data is given as 41. To find the missing data value, we can find the largest and smallest data values from the six given values:
Largest data value = 32
Smallest data value = 12
Now we can use the range formula to find the missing data value:
Range = Largest data value - Smallest data value
41 = 32 - 12
41 = 20
Therefore, the missing data value must be 41 less than the largest data value:
32 - 41 = -9
So, the missing data value is 9.
