1. Thirty women were examined in a hospital by a doctor and the number of heartbeats per minute were recorded and are summarised as follows. Find the mean heartbeats per minute for these women, choosing a suitable method.

Solution:

From the given data, let us assume the mean as A = 75.5

xi = (Upper limit + Lower limit)/2

Class size (h) = 3

Now, find the ui and fiui as follows:

Mean = x̄ = A + h∑fiui /∑fi 

= 75.5 + 3×(4/30)

= 75.5 + 4/10

= 75.5 + 0.4

= 75.9

Therefore, the mean heart beats per minute for these women is 75.9
