A group of five individuals with high blood pressure were given a new drug that was designed to lower blood pressure. Systolic blood pressure was measured before and after treatment for each individual, with the following results:

Let μX represent the population mean before treatment and let μY represent the population mean after treatment. Find a 90% confidence interval for the difference μD=μX−μY . Round the answers to three decimal places.

The 90% confidence interval is

Suppose two countries, home and foreign, produce two goods, timber and televisions. Assume that land is specific to timber, capital is specific to televisions, and labor is free to move between the two industries. When the Home country moves into doing free trade with the Foreign country, the Home country exports timber.

True or False. Explain

1. The Home country produces only timber under free trade.

2. Going from closed economy to free trade, the opportunity cost of TV increases in the home country.

3. Going from closed economy to free trade, there is no change in the real wage for timber, because it is equal to MPL_Timber under both closed economy and free trade.

4. Going from closed economy to free trade, MPK increases.

5. Going from closed economy to free trade, the landowners' living standards increase.
