Answer 1

Answer:

149.5 - 153.5.

Step-by-step explanation:

Consider the classes 150 - 153 and 154 - 157.

The lower limit of 154 - 157 = 154  

The upper limit of 150 - 153 = 153  

The difference = 154 - 153 = 1  

Half the difference = 1/2 = 0.5

So, the new class interval formed from 150 - 153 is (150 - 0.5) - (153 + 0.5), i.e., 149.5 - 153.5.
