Question
In one university, language professors incorporated a 10-week extensive reading program to improve students' Japanese reading comprehension. The professors collected 271 books originally written for Japanese children and required their students to read at least 40 of them as part of the grade in the course. The books were categorized into reading levels (color-coded for easy selection) according to length and complexity. Complete parts a through c.
Reading levels for the 271 books are below.
a. Compute the relative frequencies in each category.
Reading Level Number
Relative Frequency
Level 1 (Red) 35
Level 2 (Blue) 77
Level 3 (Yellow) 50
Level 4 (Pink) 89
Level 5 (Orange) 17
Level 6 (Green) 3
Total 271
* Would you please round those relative frequencies (Answers) to the nearest thousandth?. Thank you

Explanation / Answer
Total reading level = 271
Relative Frequency For Level 1 (Red) 35 = 35/271 = 0.1291
Relative Frequency For Level 2 (Blue) 77 = 77/271 = 0.2841
Relative Frequency For Level 3 (Yellow) 50 = 50/271 = 0.1845
Relative Frequency For Level 4 (Pink) 89 = 89 /271 = 0.3284
Relative Frequency For Level 5 (Orange) 17 = 17/271 = 0.0627
Relative Frequency For Level 6 (Green) 3 = 3 / 271 = 0.0110
0.1291 + 0.2841 + 0.1845 + 0.3284 + 0.0627 + 0.0110 = 0.9998
