Rock and roll. 30
Rap. 32
Jazz. 17
Classical. 16
Alternative. 28
All students enrolled at a school took a survey of their favorite type of music. If the school has 1599 students predict how many students favorite music is rock and roll
To predict how many students' favorite music is rock and roll, we can use the proportion of students who chose rock and roll in the survey.
The total number of students who participated in the survey is 30 (rock and roll) + 32 (rap) + 17 (jazz) + 16 (classical) + 28 (alternative) = 123 students.
The proportion of students who chose rock and roll is 30/123 = 0.2439.
To predict how many out of 1599 students favor rock and roll, we can multiply the proportion by the total number of students:
0.2439 * 1599 = 390.26
Therefore, we can predict that approximately 390 students' favorite music is rock and roll.
