Answer 1

Class limit	Frequency	Class mid point	Class boundaries

Class boundaries are the midpoints between the upper class limit of a class and the lower class limit of the next class in the sequence.

Each class has an upper and lower class boundary.

For the first class :1435 - 1457

The lower class boundary is the mid point between 1434 and 1435.

(1434 + 1435)/2 = 1434.5

The upper class boundary is the mid point between 1457 and 1458.

(1457 + 1458) = 1457.5

 

For the second class :1458 - 1480

The lower class boundary = (1457 + 1458)/2 = 1457.5

The upper class boundary = (1480 + 1481)/2 = 1480.5

 

For the third class: 1481 - 1503

The lower class boundary = (1480 + 1481)/2 = 1480.5

The upper class boundary = (1503 + 1504)/2 = 1503.5

 

For the fourth class: 1504 - 1526

The lower class boundary = (1503 + 1504)/2 = 1503.5

The upper class boundary = (1526 + 1527)/2 = 1526.5

 

For the fifth class: 1527 - 1549

The lower class boundary = (1526 + 1527)/2 = 1526.5

The upper class boundary = (1549 + 1550)/2 = 1549.5.
