The table below gives information on the CPI and the monthly take-home pay of Bill Jones, an employee at the Ford Canada.

(a) What is the purchasing power of the dollar for 2007 based on the period 2002? (Round the final answer to 5 decimal places.)

(b) Determine Mr. Jones’ "real" monthly income for 2007. (Round the final answer to 2 decimal places.) .

(c) What is the purchasing power of the dollar for 2010 based on the period 2002? (Round the final answer to 5 decimal places.)

(d) Determine Mr. Jone's "real" monthly income for 2010. (Round the final answer to 2 decimal places.)

Part 1. Describe the boundaries of the triangle with vertices (0, 0), (2, 0), and (2, 6). (a) Describe the boundary with the top function, bottom function, left point, and right point. (b) Describe the boundary with the left function, right function, bottom point, and top point.

Part 2. Consider the triangle with vertices (0, 0), (3, 0) and (6, 6). This triangle can be described using only one of the two perspectives presented above: top-bottom or left-right. Explain which perspective can be used and describe the region using that perspective. Write and label the boundary functions and points. If you want to use the other perspective, then you’ll have to split the shape into two different parts, each of which can be described using that perspective.

Part 3. Split the triangle in the previous exercise into two triangles. Describe each triangle as a region using the perspective you didn’t use in the previous exercise.

1. A survey about same-sex marriage used a random sample with 1200 adults. The results showed that 30% favored legal marriage, 32% favored civil unions, and 38% favored no legal recognition. Computer the right boundary at the 91% C.L. for the proportion of adults who favor the “legal marriage” position.

2. A survey about same-sex marriage used a random sample with 1200 adults. The results showed that 30% favored legal marriage, 32% favored civil unions, and 38% favored no legal recognition. Computer the right boundary at the 94% C.L. for the proportion of adults who favor the “civil union” position.

3. A survey about same-sex marriage used a random sample with 1200 adults. The results showed that 30% favored legal marriage, 32% favored civil unions, and 38% favored no legal recognition. Computer the right boundary at the 97% C.L. for the proportion of adults who favor the “no legal recognition” position.

Table 10.7 lists the mean salary, in thousands of dollars, of faculty on nine-month contracts in U.S. institutions of higher education in 2013-2014, by gender and academic rank.

(a) Suppose that gender is the explanatory variable. Identify the response variable and the control variable.

(b) Describe the bivariate relationship between gender and salary.

(c) Describe the relationship between gender and salary, controlling for academic rank.

(d) A hypothesis of interest for these variable is "Controlling for academic rank, annual salary and gender are independent." Draw a causal diagram that is consistent with this hypothesis. Refer to your interpretation inpart (c), and commeng on whether the gypthesis seems plausible.

(e) Is it possible that the overall difference between mean income of men and women could be larger than the difference for each academic rank? (It nearly is.) Explain how or how not.

Academic Rank

Gender Professor Associate Assistant Instructor Overall
Men 115.5 81.2 68.5 59.6 85.5
Women 98.1 75.4 63.6 56.9 70.4

Part I - Do Students Really Cheat? (30%)

In a recent poll 400 students were asked about their experiences with witnessing academic dishonesty among their classmates. Suppose 172 students admitted to witnessing academic dishonesty, 205 stated they did not and 23 had no opinion. Use the sign test and a significance of 0.05 to determine whether there is a difference between the number of students that have witnessed academic dishonesty compared to those that have not.

In 2002 the mean age of an inmate on death row was 40.7 years with a standard deviation of 9.6 years. A sample of 32 current death row inmates shows a mean age of 38.9 years. Does this indicate that the mean age of death row inmates is less than in 2002?

A sheet of metal of 2 m ´ 2 m and 1.5 mm thickness is being tested in a wind tunnel.

A sheet of metal of 2 m ´ 2 m and 1.5 mm thickness is being tested in a wind tunnel.

a. Calculate the critical velocity, in m/s, at which the boundary layer will remain laminar.

b. For an upstream velocity of 35 m/s, what percentage of the metal sheet surface will have a laminar boundary layer.

c. For each of the previous cases (all laminar B.L and mixed laminar/turbulent B.L), calculate the drag force on the plate, in N. Use Table 9.3 to calculate the appropriate drag coefficients.
