Step-by-step explanation:
we know that
The high school graduating class of 2010 was 260 people
5 years later the high school graduating class was 320 people
In this problem
260 people represent the 100%
so
using proportion
Find out what percentage represent the difference (320-260)=60 people
Let
x -----> the percentage

Answer:
4
Step-by-step explanation:
Class width is said to be the difference between the upper class limit and the lower class limit consecutive classes of a grouped data. To calculate class width, this formula can be used:
CW = UCL - LCL
Where,
CW= Class width
UCL= Upper class limit
LCL= Lower class limit
From the table above:
For class 1, CW = 64 - 60 = 4
For class 2, CW = 69 - 65 = 4
For class 3, CW = 74 - 70 = 4
For class 4, CW = 79 - 75 = 4
For class 5, CW = 84 - 80 = 4
Therefore, the class width of the grouped data = 4
