Answer 7

The Morning News radio station is interested in predicting the proportion of registered voters who support an increase in the state sales tax. Listeners were asked to go to the station's website and indicate whether they favored an increase in the tax in order to support the State Park system. 1744 listeners logged on and 922 were against the increase. The population of interest is:


All people who listen to the station
The 1744 listeners who logged in and indicated their preference
The 922 listeners who were against the issue
All registered voters
Only the portion of the 1744 listeners who voted that are actually registered to vote

Answer 8

I thought of the second one.

Answer 9

i guess so but I'm not really sure

Answer 10

Have any ideas @texaschic101

Answer 11

I do not think it is the 2nd one....because they are looking for those that support the increase, not the ones that do not support it

Answer 12

but then again, if you know who is against it, then you can figure out who is for it

Answer 13

So, the third makes sense to use?

Answer 14

I am sorry but I am not sure

Answer 15

Okay, I will go with the best one I think will work.
