Okun's law This exercise uses the notion of gross domestic product from Exercise 3. Okun's law gives the (empirically observed) correspondence between a change in the unemployment rate and a change in the gross domestic product. Let g be the percentage change in the gross domestic product over a year, and let u be the change, in percentage points, of the unemployment rate over that year. One form of Okun's law states that g = 3 – 2u. For example, if the unemployment rate is unchanged over a year, then u = 0 and g = 3 – 2 x 0 = 3, so the gross domestic product changes by 3%. a. Suppose that in a year, the unemployment rate rises from 3% to 5% (so u = 2 percentage points). According to Okun's law, what is the percentage change in the gross domestic product? b. From 2013 to 2014, the unemployment rate fell from 7.4% to 6.2%. What does Okun's law give for the percentage change in the gross domestic product? (Note:In this case, u is a negative number.)

How hot is the air in the top (crown) of a hot air balloon? Information from Ballooning: The Complete Guide to Riding the Winds, by Wirth and Young (Random House), claims that the air in the crown should be an average of 100°C for a balloon to be in a state of equilibrium. However, the temperature does not need to be exactly 100°C. What is a reasonable and safe range of temperatures? This range may vary with the size and (decorative) shape of the balloon. All balloons have a temperature gauge in the crown. Suppose that 57 readings (for a balloon in equilibrium) gave a mean temperature of x = 97°C. For this balloon, σ ≈ 16°C.

6 Trout population Suppose 200 trout are caught, tagged, and released in a lake's general population. Let T denote the number of tagged fish that are recaptured when a sample of n trout are caught at a later date. The validity of the mark- recapture method for estimating the lake's total trout popula- tion is based on the assumption that Tis directly proportional to n. If 10 tagged trout are recovered from a sample of 300, estimate the total trout population of the lake.
