A newspaper conducted a statewide survey concerning the 2008 race for state senator. The newspaper took a random sample (assume it is an SRS) of 1200 registered voters and found that 620 would vote for the
Republican candidate. Let p represent the proportion of registered voters in the state that would vote for the
Republican candidate.
Use Scenario 8-2. A 90% confidence interval for p is
a. 0.517 +0.014.
b. 0.517 +0.022.
c. 0.517 + 0.024.
d. 0.517 +0.028.
e. 0.517 +0.249.

          √25                                         √33               √36      

i made this little number line up there for a visual example. : d

to find √33, you take the nearest root vales you know right off the bat. √25 and √36 which is 5 and 6, correct? and on the number line, you can see that √33 falls closer to √36, 6. so we know that √33 is going to be 5 point. something, right? but because 33 is so close to six, it is going to be a higher number for 5 point. something. so it is approximately 5.7

the result is 17 - 10n
