Ministry of Natural Resources could study the effects on bats, butterflies, migratory birds. and aquatic species. The studies are now close to completion. allowing a number of wind farm projects to seek approval once again. Research the various stakeholders and their viewpoints. Stakeholders may include, but are not limited to, residents of the area, government, and electric generation companies. What are some expenses for developing an offshore wind energy project?

The director of graduate studies at a large college of business has the objective of predicting the grade point average (GPA) of students in an MBA program. The director begins by using the Graduate Management Admission Test (GMAT) score. A sample of 20 students who have completed two years in the program is selected and stored in GPIGMAT.

Determine the coefficient of determination, $r^2$, and interpret its meaning in this problem.

Cost of Massage Therapy Sessions. The Wall Street Journal reported on several studies that show massage therapy has a variety of health benefits and it is not too expensive. A sample of 10 typical one-hour massage therapy sessions showed an average charge of $\$ 59$. The population standard deviation for a one-hour session is $\sigma=\$ 5.50$.

b. Using $95 \%$ confidence, what is the margin of error?

Which of the following is a potential problem with case studies? a. They provide too much detail and the researcher is likely to lose track of the most important facts. b. They are generally too expensive to be economical. c. They may be misleading because they don't fairly represent other cases. d. They are technically difficult and most researchers don't have the skills to do them properly. e. The dependent variable is difficult to operationally define in a case study.

A laser ring gyroscope, or laser ring gyro (Figure 5), measures rotation using the constancy of the speed of light in any frame. Laser ring gyros have uses in navigation systems on aircraft and in detailed studies of Earth's rotation. Research this application of relativity, and summarize your findings in a brief report. Include a description of two applications of laser ring gyros and an analysis of the technology behind them.

Studies show that when environmental factors impose an upper bound on the possible size of a population P(t), the population often tends to grow in such a way that the percentage rate of change of P(t) satisfies $\frac{100 P^{\prime}(t)}{P(t)}=A-B P(t)$ where A and B are positive constants. Where does the graph of P(t) have an inflection point? What is the significance of this point? (Your answer will be in terms of A and B.)

Scientific studies on meditation have revealed that:

a. experienced meditators enter a drowsy, trance-like state that is essentially no different from resting with your eyes closed

b. meditation’s benefits can best be explained by nonstate social-cognitive processes

c. meditation can relieve stress but has no effect on cognition, emotion, or other psychological processes

d. even beginning meditators can experience improvements in attention and memory

For the following reports about statistical studies, identify the following items (if possible). lf you can't tell, then say so-this often happens when we read about a survey. A company packaging snack foods maintains quality control by randomly selecting 10 cases from each day's production and weighing the bags. Then they open one bag from each case and inspect the contents.

For statistical studies, U.S. states are often grouped by region: Northeast, Midwest, South, and West. The 1965 total public school enrollment (in millions) in each region was 8.8, 11.8, 13.8, and 7.6, respectively. The projected 2020 enrollment was 7.8, 10.8, 20.4, and 13 .6, respectively. Use two pie graphs to present this data and discuss any trends suggested by your graphs.

How will the following changes affect the natural rate of unemployment?

a. The government reduces the time during which an unemployed worker can receive benefits.

b.More teenagers focus on their studies and do not look for jobs until after college.

c. Greater access to the Internet leads both potential employers and potential employees to use the Internet to list and find jobs.

d. Union membership declines

A new muscle relaxant is available. Researchers from the firm developing the relaxant have done studies that indicate that the time lapse between administration of the drug and beginning effects of the drug is normally distributed, with mean $\mu=38$ minutes and standard deviation $\sigma=5$ minutes. The drug is administered to one patient selected at random. What is the probability that the time it takes to go into effect is 35 minutes or less?

Studies show that the concentration of PCBs is much higher in malignant breast tissue than in normal breast tissue. If a study of 50 women with breast cancer reveals an average PCB concentration of $22.8 \times 10^{-4} \operatorname{gram},$ with a standard deviation of $4.8 \times 10^{-4} \mathrm{gram},$ is the mean concentration of PCBs less than $24 \times 10^{-4} \text { gram? }$

One of the earliest studies in allometry was performed by Bryan Robinson during the eighteenth century. He found that the pulse rate of an animal could be approximated by $f(x)=1607 x^{-0.75}$. The input $x$ is the length of the animal in inches, and the output $f(x)$ is the approximate number of heartbeats per minute.

(a) Use $f$ to estimate the pulse rates of a $2$-foot dog and a $5.5$-foot person.

(b) What length corresponds to a pulse rate of $400$ beats per minute?
