The answer to the following question is : 30.71
Step by step explanation:
The class given frequency
(no of patients) no of hospital visit days
0-10 2
10-20 6
20-30 9
30-40 7
40-50 4
50-60 2
the midpoint of the class are:
5, 15, 25, 35, 45, 55.
multiply midpoint with the frequency of the table.
we get,
10, 90, 225, 245, 180, 110
adding the multiplied column, we get
10+90+225+245+180+110 = 860
adding frequency we get,
2+6+9+7+4+2 = 28
The average is cumulative frequency ÷ frequency added.
860÷28
= 30.71
Hence the average people visiting the hospital is 30.71
