Recall the study about anchoring from Exercise 6.2.16, in which students estimated the population of Milwaukee after some had been told about Chicago and others about Green Bay.
a. Describe in words the parameter(s) of interest in the con- text of this study.
b. In the context of the parameter(s) described in part (a), express the null and alternative hypotheses for testing whether the class data give strong evidence in support of the anchoring phenomenon described above. If you use symbols, make sure to define them.
c. Check whether the conditions for the validity of the theory-based t-test to compare two means are satisfied here.
d. Use appropriate technology (an applet or a statistical soft- ware package) to conduct a t-test of significance of the hypotheses that you stated in part (b). Report the test statistic and p-value
e. State your conclusion in the context of the study, being sure to comment on statistical significance.
f. Determine and interpret the 95% confidence interval using a theory-based approach for the parameter(s) of interest in the context of the study.
g. Comment on causation and generalization for this study.
