The 2010 General Social Survey asked a random sample of Americans about whether they generally trust people. The following table classifies responses by the highest educational degree achieved by the person:

a. Identify the explanatory and response variables in this study.

b. For each category of educational attainment, calculate the proportion indicating they generally trust people. Also produce a graph to display these proportions. Comment on what the calculations and graph reveal.

c. State the null hypothesis to be tested from these data.

d. Calculate the value of the MAD statistic for these sample data.

e. Conduct a simulation-based analysis using the MAD statistic. Submit a screen capture of the null distribution and report the approximate p-value.

f. Interpret what the p-value says in this context.

g. Would you reject the null hypothesis at any reasonable significance level?

h. State your conclusion about the strength of evidence.
