A candidate for a political office claims that he will win the election. A poll is conducted, and 35 of 150 voters indicate that they will vote for the candidate, 100 voters indicate that they will vote for his opponent, and 15 voters are undecided.
a. What is the population parameter of interest?
b. What is the value of the sample statistic that might be used to estimate the population parameter?
I would focus on the undecided. However, in this case, I would look at the 100 voters, on how firm their committment is, and what might change them.
I am still so confused....the population parameter of interest isn't 150?
The value of the sample statistic isn't 100?
I'm sorry I am so lost with Statistics...one of the hardest classes I've dealt with yet :( Please help me...
This might help you.

would this be right?
the population parameter of interest is 45%?
the value of the sample statistic is 50%??
a. The population parameter of interest in this scenario is the proportion or percentage of voters who will vote for the candidate.
b. The value of the sample statistic that might be used to estimate the population parameter is the sample proportion or percentage of voters who indicate that they will vote for the candidate. To calculate this, divide the number of voters who indicate they will vote for the candidate (35) by the total number of voters in the sample (150). In this case, the sample proportion is 35/150 = 0.2333 or 23.33%.
