(a)
To calculate: The number of units of X must be purchased to retain the same level of utility if the consumer purchases 9 units of Y. Suppose that the utility function for two goods X and Y is given by
(b)
To calculate: The number of units of Y must be purchased to retain the same level of utility if the consumer purchases 81 units of X. Suppose that the utility function for two goods X and Y is given by
(c)
To graph: The indifference curve for the utility level found in parts (a) and (b). Use the graph to confirm the answers to parts (a) and (b). Suppose that the utility function for two goods X and Y is given by

- Exercise 2. Marginal and Conditional Relationships can be Very Different. For 100 mild cases of eczema, a new treatment had a higher cure rate than the old treatment (33.3% of 90 vs. 20% of 10). For 100 severe cases of eczema, again the new treatment had a higher cure rate than the old treatment (60% of 20 vs. 50% of 80). Over all 200 eczema cases, however, the old treatment had a higher cure rate than the new treatment- i.e. Simpson's Paradox strikes again. (a) Compute the overall cure rates for the new and old treatments. (b) Which treatment, old or new, would you choose and why?arrow_forward20) A study in the Los Angeles Times reported that the number of liquor stores in a neighborhood has a strong positive linear association with the amount of crime in that neighborhood. What can you determine about the relationship between the number of liquor stores and the amount of crime? Neighborhoods with a higher number of liquor stores tend to have a higher amount of crimes. People who live in neighborhoods with more liquor stores commit more crimes. If we decrease the number of liquor stores in a neighborhood, the amount of crimes will decrease. No conclusions can be drawn without seeing a scatterplot of the data.arrow_forward
