23 / 4 = 5 . 7 Hours

21 / 2 = 10 . 5 Hours

3 Hours

Step-by-step explanation:

15.5 + 2.7 + 5.7 + 10.5 + 3 Hours

Answer 2

Answer:

Step-by-step explanation:

Given,

3 1/2 = 7/2 = 3.50

2 3/4 = 11/4 = 2.75

11/4 = 2.75

2 1/2 = 5/2 = 2.50

3 = 3

Now, we know that,

Mean = sum of frequencies / total number of frequencies = (3.5 + 2.75 + 2.75 + 2.5 + 3) / 5 = (14.5) / 5 = 2.9

Now converting 2.9 into fraction that is,

2.9 = 29/10 = 2 9/10

Hence, mean = 2 9/10 days
