Use the following to answer the questions below:

In a Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12.


Suppose you want to estimate the proportion of local adults who are dissatisfied with the education students receive in kindergarten through grade 12 with 95% confidence and a 5% margin of error. If you suspect that local adults won't differ drastically from those Gallup used, how many people should you sample?

▸ You should sample 358 local adults.

▸ You should sample 343 local adults.

▸ You should sample 383 local adults.

▸ You should sample 369 local adults.
