Suppose that Lorenzo, an economist from a university in Arizona, and Neha, an economist from a school of industrial relations, are arguing over government bailouts. The following dialogue shows an excerpt from their debate: Neha: Thanks to recent financial crises, the concept of bailouts is a hot topic for debate among everyone these days. Lorenzo: Indeed, it's gotten crazy! A government bailout of severely distressed financial firms is unnecessary because free markets will properly price assets. Neha: I don't know...

A group of high-school parents in Tucson, Arizona, in conjunction with faculty from the University of Arizona, claim that young women in the Tucson high schools not only are called on less frequently, but receive less time to interact with the instructor than do young men. They would like to see the school district hire a coordinator, spend money (and time) on faculty workshops, and offer young women classes on assertiveness and academic communication. To make things simple, assume that...

This semester, there are 259 professors at University A and 128 sent in midterm progress reports. Again, assume the professors at University A are representative of all professors. (a) Construct a 95% confidence interval for the proportion of all professors who sent in midterm progress reports this semester, and then interpret it. Note: Remember that a confidence interval is made up of three components: pˆ, z, and n. You should have all the information you need to construct the interval....

Beatriz enjoys writing and uses a large amount of paper. Currently, paper costs $2.00 for 100 sheets. The formula for her demand curve is S=525−50PS, where PS is the price of 100 sheets and S is the number of packages of 100 sheets. The governor of her state has proposed taxing paper at the rate of $1.50 for each 100 sheets. Assume this policy would increase the price of paper to $3.50 (including tax). Draw Beatriz's demand curve. Instructions: Use...
