Question

Madhu work two and half hours on Monday 31 by 4 hours on Tuesday and to 3 by 4 hours on Wednesday what is the mean number of hours she walked on the series​

Answer 1

Answer:

On an average Madhu worked for 3.6 hours.

Step-by-step explanation:

Mean = Sum of all observations / total number of observations

The first observation is 2 and half which is a mixed fraction, after solving it we get 5/2

Here the sum of all observations is

= 5/2 + 31/4 + 3/4

= 5/2 + 34/4

= 20 + 68 / 8

= 88 / 8

= 11

So sum of all observations is 11 and the number of observations is 3

Substitute the values and you get

Mean = 11/3

Mean = 3.6 ( approx )

Therefore on an average Madhu worked for 3.6 hours.

Hope this will help and mark my answer as brainliest if this helps.
