Answer please

1. Classify the following data by taking class interval such that their values are 17,22,27,32, and so on 30 42 30 54 40 48 15 17 51 42 25 41 30 27 42 36 28 26 37 54 44 31 36 40 36 22 30 31 19 48 16 42 32 21 22 46 33 41 21

What you provided here is simple data??.17 , 22, 27, 32 ,??
And no other information has been provided by you. If looking at the data, the differene is?
22 ? 17 = 5.
27 ? 22 = 5.
32 ? 27 = 5.
So it is obvious that your so on data would include?.32 + 5 = 37 , 37 + 5 = 42, 42 + 5 = 47 and ?..
Now we know that the mid values in the given data are?..17 , 22, 27, 32, 37, 42, 47 and so on..
So perfect distribution would be?..as below.
Class-Interval Mid-Point
15 ? 19 17
20 ? 24 22
25 ? 29 27
30 ? 34 32
35 - 39 37 and so on
