Question

for a school project, lola wants to know how many of her city’s 10,000 residents watched the high school state championship football game last weekend. lola randomly selects 100 residents and finds that 34 of them watched the championship game.
estimate the number of residents in lola’s city who watched the championship game.
340
3,400
6,600
9,660

Explanation:

Step1: Find the proportion in the sample

The proportion of residents who watched the game in the sample is $\frac{34}{100}$.

Step2: Apply the proportion to the total population

To estimate the number in the total population of 10,000, we multiply the proportion by the total: $10000\times\frac{34}{100}$.
Simplify the calculation: $10000\times0.34 = 3400$.

Answer:

3,400
