The number of students in the school favoring the music class over other subjects.
Answer to Problem 27CCR
The given data is not representative of the entire school. It isn’t possible to determine how many students would say their favorite class is music.
Explanation of Solution
Given: 63 out of 105 students in the band chose music as their favorite class. The whole school has 848 students.
The given group of students being in a band obviously likes music more and hence the group is biased which is why more of them chose music as their favorite class. Hence, the results are not representative of the entire school.
Out of 848 students, it isn’t possible to figure out how many students will choose music as their favorite class. At bare minimum all 63 students of the band will choose music as their favorite class but there can be other students who do not participate in the band but do like music and can possibly choose music as their favorite class.
Thus, it isn’t possible to correctly determine with certainty how many students would say that music is their favorite class.

- Trolley of the overhead crane moves along the bridge rail. The trolley position is measured from the center of the bridge rail (x = 0) is given by x(t) = 0.5t^3-6t^2+19.5t-14 : 0 <= t <= 3 min. The trolley moves from point A to B in the forward direction, B to C in the reverse direction and C to D again in the forward direction.
