We have a flat (k = 0), homogenuous and isotropic universe with a cosmological constant \Lambda and one other type of material satisfying p = w\rho with a density thus given by \rho = \rho wR−3(1+w) and \rho w is a constant. The value of the Hubble constant at the present time t0 is H0 and the scale factor R(t0) = 1.

In many cases, companies that enter a market after innovative products have been introduced can achieve long-term competitive advantages by continuing to develop a better mousetrap. For example, MicroPro was the first company to introduce a word processing program, but SSI cornered a large market share when it introduced the Word Perfect program. Today, however, Microsoft's Word is the dominant word-processing software program and has continued to endure due to the popularity of the Microsoft Office Suite of products. MicroPro's WordStar possessed a ____ advantage while Microsoft enjoyed a ____ advantage. a. first-mover; late-mover b. economic; technological c. late-mover; first-mover d. sustainable; unsustainable e. sustainable; late-mover

7. (10 points) The college instructor wants to know if there is a difference between two exam scores among a group of students in his Calculus 1 class. He records the exam score for both exams in data file Q4 for any particular student selected for the study. Which hypothesis test should he conduct to determine if there is a difference between exam scores among both of their exams? Test at the \( 5 \% \) level of significance whether the data provide sufficient evidence to conclude that exam 1 has lower mean scores than exam 2. 8. (15 points) A public health researcher is interested in social factors that influence heart disease. He surveys 50 towns and gathers data on the percentage of people in each town who smoke, the percentage of people in each town who bike to work, people's age, blood pressure, diabetes, and the percentage of people in each town who have heart disease (see Q5). (a) Assess each variable separately first (obtain measures of central tendency and dispersion, frequency distributions, and graphs) (b) Assess the relationship of each independent variable, one at a time, with the dependent variable and the relationships between all of the independent variables with each other (calculate the correlation coefficient and obtain a scatter plot). Are the two variables linearly related? (c) Which variable is the best predictor of heart disease? Why? (d) Run a simple linear regression to predict heart disease based on the best predictors. (e) Interpret your regression model based on the \( R \) output

Sketch the essential features of the vibrational spectrum of NO if it behaved as a simple harmonic oscillator. Sketch a second spectrum that shows the features of the spectrum as if the molecule behaved as an anharmonic oscillator. Indicate clearly the differences in the spectrum arising from the different models.
