Question

The results of a poll show that the percent of people who want a toll road is in the interval (46%, 84%) . There are 268,548 people in the city. What is the interval estimate for the number of people who want this toll road in their city?

Answer 1

Answer: To estimate the number of people who want the toll road in their city, we can use the percentage range provided and calculate the interval estimate. Here's how you can do it:

• Find the lower bound of the percentage range: 46% of 268,548 = 0.46 * 268,548 = 123,442.08 (rounding down to 123,442).

• Find the upper bound of the percentage range: 84% of 268,548 = 0.84 * 268,548 = 225,607.92 (rounding up to 225,608).

Therefore, the interval estimate for the number of people who want the toll road in their city is (123,442, 225,608).
