0.493

Step-by-step explanation:

The sample proportion of voters planned to vote for Republican candidate can be calculate by dividing the number of voters planned to vote for Republican candidate in a sample to the registered voters in a sample.

It can be written as

p=x/n where x is number of voters planned to vote for Republican candidate and n is number of registered voters in a sample.

p=170/345=0.4928=0.493 or 49.3%

Thus, the sample proportion of voters who planned to vote for the Republican candidate is 0.493.
