A city council sends out a survey to city residents to determine the
support for a new school being built downtown. The survey asks residents whether they support the new school being built and their location in town. Out of those who respond, 376 of the 64 residents surveyed in Ward 1 support the new school being built, while 214 of the 398
residents surveyed in Ward 2 support the new school. Assuming the location of residents has no association with supporting the new school being built, the probability of the results of the survey being due to chance is calculated to be 0.12. Interpret the result of this calculation.
Select the correct answer below:
1- The council can expect 376 of every 641residents in Ward 1 to be in favor of building the new school.
2- The results of the survey are statistically significant at the 0.05 level in showing that the location of city residents has an association with support for building the new school.
3- The results of the survey are not statistically significant at the 0.05 level in showing that the location of the city's residents has an association with support for building the new school.
4- The location of city residents is not associated with support for the new school.
