Suppose there are 8,000 people at a basketball game. You survey a random sample of 400 spectators and gather the following information: Estimate the number of people at the event who are under 30 year

Answer 1

To estimate the number of people at the event who are under 30 years old, we can use the percentage of individuals under 30 in our random sample and apply it to the entire population of 8,000 spectators.

From the random sample of 400 spectators, let's say that 40% of them are under 30 years old. Therefore, we can estimate that 40% of the total population are under 30 years old.

Estimated number of people under 30 years old = 0.40 * 8,000 = 3,200

So, we estimate that there are approximately 3,200 people under 30 years old at the basketball game.
