Data on motor power (in horsepower) and fuel efficiency (in miles per gallon) was recorded from 31 classic vehicle models from the early 1970s. The scatterplot of the data appears below. 7. (3 points) Select the true statements about the regression line shown in the scatterplot. Indicate all true statements. ?The regression line will have a negative intercept. The regression line can be used to predict the fuel efficiency (mpg) of a classic vehicle model based on the vehicle's horsepower (hp). The regression line can be used to predict the horsepower (hp) of a classic vehicle model based on the vehicle's fuel efficiency (mpg). The $R^2$ value for this regression model will be negative.

Problem # 1 Using the data below you are to select concentrations of initiator and CTA that will give poly(vinyl acetate) with an initial molecular weight (assuming disproportion termination only) of 15,000. The polymerization (at 60°C) should be 50% complete in 8 min. Reactant Monomer: vinyl acetate FW Initial Concentration (g/l) 86.09 500.0 Initiator: 2,2'-azo-bis-2-isobutyl-4-methylvaleronitrile 332 Transfer agent: benzyl mercaptan 124.21 Solvent: methanol to make 1 L, $k_i$=3.78x10$^{-4}$ s$^{-1}$, $k_p$=15x10$^3$ L/mol-s, $k_t$=600x10$^6$ L/mol-s, $C_s$=0.885 Problem # 2 The molecular weight of polymer when vinyl butyrate is polymerized in an inert solvent is 500,000. With all other conditions the same, addition of 5 g/l of 1-dodecanethiol decreases the molecular weight to just 150,000. What concentration of 1-dodecanethiol will give a molecular weight of 275,000 (keeping in mind that all other conditions remain the same)?

In a specific species of cattle, coat-patterning is controlled by two genes. Individuals that have at least one dominant allele for Gene C (C/-) will be black regardless of the genotype for Gene S. However, if an individual is homozygous recessive for Gene C and has at least one dominant allele for Gene S (ccS/-) it will be white with brown spots, while double heterozygotes (ccss) will be white. This is an example of: Question 6 options: Complementation Dominant Epistasis Recessive Epistasis Complete Dominance
