Step-by-step explanation:

The median class is 155 - 160.

Step-by-step explanation:

To find, the median class = ?

Class interval Frequency(f) Cumulative frequency(cf)

140-145 5 5

145-150 15 20

150-155 25 45

155-160 30 75

160-165 15 90

165-170 10 100

Total Σf = n = 100

∴ n/2=100/2=50

Median class = 155 - 160

Thus, the median class is 155 - 160.
