A researcher wants to study the academic performance of urban secondary schools in his county. He decides to measure each school's academic performance by collecting data on the percentage of students passing at least one Advanced Placement (AP) exam.The following table shows each school with the percentage of students passing at least one Advanced Placement (AP) exam.

		Table1
No.	School		Academic Performance
1	Booker T. Washington High School		3
2	Central Academy		4
3	Hsi Lai Academy		7
4	Performing Arts High School		8
5	Springfield High School		11
6	Hebrew Academy		14
7	Immaculate Conception High School		16
8	Mystic Valley Regional Charter School		17
9	West Springfield Technical High School		19
10	Buckhead Heights High School		22
11	Westwood Heights High School		23
12	Longwood Academy		25
13	Anderson Technical High School		26
14	Taylor Technical High School		29
15	Arborville High School		30
16	Inglewood Heights Academy		36
17	Robert Wood Johnson Health Academy		39
18	Metropolitan Community School		42
19	Medfield Senior High		51
20	Grover Cleveland High School		53
21	Lowell High School		58
22	Danville High School		60
23	Salaam Learning Academy		68
24	Northside College Preparatory High School		72
25	Friends Academy		80

(Note: Academic Performance is measured as the percentage of students passing at least one AP exam)

In order to organize the data in Table 1, the researcher needs to decide whether to use a grouped frequency distribution table or whether to list each possible score individually from the lowest score to the highest score (or from the highest score to the lowest score), including scores in between that have zero frequencies. If he lists all possible scores individually, the frequency distribution table would have rows. The researcher decides that a grouped frequency table would better organize this data.

Table 2 divides the range of these 25 schools' academic performance into nine intervals and gives some of their frequencies and relative frequencies. Based on the information provided in Table 1, use the dropdown menus to complete Table 2.

	Table 2
Academic Performance		Frequency	Relative Frequency
0 to 9		4	0.16
10 to 19		5	0.20
20 to 29		5	0.20
30 to 39
40 to 49		1	0.04
50 to 59		3	0.12
60 to 69
70 to 79		1	0.04
80 to 89		1	0.04
Total		25	1.0

The preceding table obeys some basic rules of grouped frequency tables.

First, the table has approximately 10 . The width of each interval is a relatively number. The bottom score in each class interval is a of the width.

In which interval would a score of 29.4 fall?

In which interval would a score of 19.6 fall?
