Question
Application 88: (10 Pts) An automotive trade association just received the results of a survey taken on the relationship between the issues of global warming and automobile gasoline emissions contributing to global warming. After reviewing the results, the members were worried that global warming and gasoline emission contributing to global warming may be the same issue. The Paired Samples Test was run on SPSS to determine whether or not there was a significant difference in the survey responses to two questions The scale used for each questions was a 7 Pt. scale: 1 Absolutely Not...7 Absolutely Does. The resulits PAIRED SAMPLES TEST T-TEST Std.

(4 Pts) Interpret the results of the test. What do the significant results state about the two issues? c)Explanation / Answer
(a)
The null hypothesis is:-
The issues of global warming and the gasoline emissions contributing to global warming are same.
(b)
The type of scale used is-
7 point Likert scale
The type of data obtained was-
Ordinal data
with values from 1 - 7
which can be considered as quantitative or numeric for this analysis.
(c)
The mean response to the concern over the issue of global warming is 4.98
The mean response to the belief that the gasoline emissions contribute to global warming is 4.62
The results of paired samples t test indicate that:
The difference in the mean respons to the concern over the issue of global warming and the belief that the gasoline emissions contribute to global warming is 0.263
This difference between the responses to the 2 issues is statistically significant (since p-value < 0.001)
We reject the null hypothesis that the issues of global warming and the gasoline emissions contributing to global warming are same.
We conclude that the belief of the people that the gasoline emissions contribute to global warming is significantly less than their concern over the issue of global warming.
