Question

pls help me solve this problem pls​

Answer 1

solution:

i)

We know that the area of the rectangles are proportional to the frequencies in a histogram.

Here the widths of the rectangles are varying. So we need to make certain modification in the length of the rectangles, so that the areas are become proportional to the frequencies.

The minimum class size is 2.

Length of a rectangle (adjusted frequency)=(minimum class size / class size of this class) × frequency.

The modified table of given data is in the attachment.

And the histogram with varying width is in the attachment.

ii)

The class interval in which the maximum number of surnames lie is 6-8
