Explanation / Answer

Solution:

   Part a) Since responses are : Vote for , Vote against and No opinon ,which makes different categories , thus the responses for this question provide categorical data.

Part b) Sample size for Gallup poll =........?

From the given question we have   Number of persons who vote for Law= 295 ,

Number of persons who vote against Law = 672 and

Number of persons who do not have any opinion about Law = 51

Thus total sample size = n = 295 + 672 + 51 = 1018

Part c) The percentage of respondents would vote for a Law increasing the gas tax = .......?

The percentage of respondents would vote for a Law increasing the gas tax = x / n

The percentage of respondents would vote for a Law increasing the gas tax = 295 / 1018

The percentage of respondents would vote for a Law increasing the gas tax = 0.2898

The percentage of respondents would vote for a Law increasing the gas tax = 28.98%

Part d) First find :

The percentage of respondents would vote against a Law increasing the gas tax = 672 / 1018

The percentage of respondents would vote against a Law increasing the gas tax = 0.6601

The percentage of respondents would vote against a Law increasing the gas tax = 66.01%

      Since the percentage of respondents would vote against a Law increasing the gas tax = 66.01% is much greater than that of Vote for a Law increasing the gas tax which is 28.98%, the results indicates general support against increasing the gas tax to improve roads and bridges and build more mass transportation.
