Question

10.1 Populations and Samples

Answer 1

Answer:

I'm glad you asked!I couldn't fully understand it so I made it the best of my ability.

Step-by-step explanation:

1.(Please,I cannot understand it .I think it is incomplete.)

2.18 out of 270 students speak 3 languages or more.So $30,330$ x $\frac{18}{270}$ = $2,002.2,002$ students.

3.We would do 5,000 x $\frac{2}{10}$ = 1,000.

4.No, the manufacturer cannot assume the prediction is valid.

The sample size of 10 is too small compared to the size of the shipment.

5.You can use random samples by using them for graphs which numbers are too big.

Answer 2

I think you can multiply how many are defective in a sample by how much more stuff there is
