Question

Alicia and Thea are in charge of determining the number of T-Shirt to order to sell in the school store. Each Student collected sampled data from the population of 300 students. Alicia surveyed 50 students in the cafeteria. Thea surveyed the first 60 students who arrived at school one morning. Use Alicia's data to estimate the number of T-Shirts they should order

Answer 1

Answer: Look at the explanation. Note that this is from the book.

Explanation:

Alicia: 30/50 = x/30

x=180

They should order about 180 T-shirts.

Thea: 51/60 = x/300

x = 255

They should order about 255.

Note that we got the 300 from what the question said of the population being 300 students.

Hope this helps you!

Answer 2

Answer: 360

Explanation:

Since we are informed from the question that Alicia surveyed 50 students in the cafeteria from the population of 300 students, it simply means that she surveyed 50/300 = 1/6 of the students.

Since Thea surveyed the first 60 students who arrived at school one morning, the number of T-Shirts taht they should order will be:

= 1/6 × x = 60

x = 60 × 6.

x = 360

They should order 360 t-shirts for the students.
