Chapter 12, Problem 8CR

To determine

To graph: the histogram from the given data.

Answer to Problem 8CR

From the histogram maximum customer come around $141-150$ and the minimum customer come around $161-170$ .

Explanation of Solution

Given:

Customers:

  $141,128,132,141,152,169,121,133,131,156,142,136,135,144,135,153$ .

Concept used:

Class interval should be same or constant.

Frequency can be varied with class interval.

Calculation:

According to the given data:

Customers:

  $141,128,132,141,152,169,121,133,131,156,142,136,135,144,135,153$ .

Divide the data into intervals, the minimum is $121$ and the maximum here is $169$ .

Divide the data into $5$ intervals.

Customers	Frequency
$121-130$	$2$
$131-140$	$6$
$141-150$	$4$
$151-160$	$3$
$161-170$	$1$

Draw and label the axes. Draw a bar to represent the frequency of each interval.

  

Hence, from the histogram maximum customer come around $141-150$ and the minimum customer come around $161-170$ .
