Question
The city council is considering a law that would ban smoking in all public facilities. A sample has been selected from the community and tested for support of the ordinance. The table showing the bivariate table is presented below. Furthermore, the data have been analyzed using SPSS, and researchers have found that the chi-square statistic is 36.1429 and the p-value is < .00001. 1) What is the null hypothesis in this study? What is the research hypothesis? 2) What are the expected values for each cell? (You need not construct a new table, just provide the four values, labeling which cell they belong to). 3) What percentage of older voters support a ban on smoking? What percentage of younger voters do? 4) What decision should the researchers make about the null hypothesis? 4) Based on your answer above, which type of error might the researchers be making? What is the probability that they are making this type of error?
