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
