Question

a choir teacher took the students who have enrolled in her class so far and classified them by which parts they sing.
tenors\t6
altos\t7
sopranos\t13
considering this data, how many of the next 32 students to join should you expect to be sopranos?
blank sopranos

Explanation:

Step1: Calculate total enrolled students

First, find the total number of students already enrolled. Add the number of tenors, altos, and sopranos: \(6 + 7 + 13 = 26\).

Step2: Find the proportion of sopranos

The proportion of sopranos among the enrolled students is \(\frac{13}{26}=\frac{1}{2}\).

Step3: Predict sopranos in next 32 students

To find the expected number of sopranos in the next 32 students, multiply the proportion of sopranos by 32: \(\frac{1}{2} \times 32 = 16\).

Answer:

16
