Question

the following data points represent the number of emails that the ceo of rock town apparel sent each day since he started using a new email client. 6,59,55,106,84,86,96 using the data, create a histogram.

Explanation:

Step1: Determine class intervals

We can choose class intervals like 0 - 29, 30 - 59, 60 - 89, 90 - 119.

Step2: Count data points in each interval

• 0 - 29: 1 (the value 6)
• 30 - 59: 2 (55, 59)
• 60 - 89: 2 (84, 86)
• 90 - 119: 2 (96, 106)

Step3: Draw the histogram

On the x - axis we have the number of emails sent (class intervals) and on the y - axis the number of days. We draw bars with heights corresponding to the counts in each class interval. For the interval 0 - 29, the bar height is 1; for 30 - 59, height is 2; for 60 - 89, height is 2; for 90 - 119, height is 2.

Answer:

A histogram with class intervals 0 - 29, 30 - 59, 60 - 89, 90 - 119 having bar - heights 1, 2, 2, 2 respectively.
