Question

A random sample of residents of the county were categorized according to gender (male or female) and whether they supported a proposal to increase the county sales tax rate by one-half percent. The table summarizes the data for the sample.

Answer 1

To test the independence of poll responses and participants' ethnic group, we can use a test of independence. This involves calculating expected values, the chi-square statistic, and comparing it to a critical value.

Step-by-step explanation:

The question is asking whether the poll responses are independent of the participants' ethnic group. To test this, we can use a test of independence. We can calculate the expected values for each cell in the table by multiplying the row total and column total and dividing by the total sample size. Then, we can calculate the chi-square statistic by summing the squared differences between the observed and expected values, divided by the expected values. Finally, we can compare the chi-square statistic to the critical value from the chi-square distribution with the appropriate degrees of freedom to determine if there is a significant relationship between the variables.

Answer 2

I fail to understand what exactly you are asking. Could you be more specific and include and image of the table maybe?
