To find the number of days the friend received 19 or fewer emails in a day, we can create a frequency distribution table with the data given:
Number of emails | Number of days
---|---
0-4 | 2
5-9 | 5
10-14 | 7
15-19 | 5
20-24 | 1
From the table, we can see that the friend received 19 or fewer emails on 2 + 5 + 7 = 14 days. Therefore, the correct answer is (c) 12, since this is the number of days when the friend received 19 or fewer emails in each of those days.
the number of emails a friend receive each day during last 20 days is shown below. what number of days she receive 19 or fewer e-mails in a day? a.7 b. 11 c. 12 d. 15
