of the 50 states and the District of Columbia. 

The leftmost bar in the histogram covers per cent of never-married women ranging from about 

(a) $20\%$ to $24\%$

(b)$20\%$ to $22\%$

(c) $0\%$ 

(d) $0\%$ to $5\%$ 

(e) None of these.

Step-by-Step Solution

Answer

The accurate answer is (b) $20\%$ to$22\%$

Step 1: Given information

Given :

Theory used :

The histogram is a popular graphing tool. It is used to summarize discrete or continuous data that are measured on an interval scale. It is often used to illustrate the major features of the distribution of the data in a convenient form.

Step 2: Explanation for correct option

On the horizontal axis, the leftmost bar represents values between $20\% \mathrm{and} 22\%.$

This suggests that the leftmost bar represents roughly $20\% \mathrm{to} 22\%$ of never-married women.

Step 3 : Explanation for incorrect option

(a) The leftmost bar in the histogram doesn't cover per cent of never-married women ranging from about $20\% \mathrm{to} 24\%$

(c) The leftmost bar in the histogram doesn't cover per cent of never-married women ranging from about $0\%$

(d) The leftmost bar in the histogram doesn't cover per cent of never-married women ranging from about $0\% \mathrm{to} 5\%$

(e) The leftmost bar in the histogram doesn't cover per cent of never-married women ranging from about "None of these".
