An economist believes there is a linear relationship between the marketprice of a particular commodity and the number of units suppliers of thecommodity are willing to bring to the marketplace. Two sampleobservations indicate that when the price equals $15 per unit, the weekly supply equals 30,000 units; and when the price equals $20 per unit, theweekly supply equals 48,000 units
(i) If price per unit, p, is plotted on the horizontal axis and the quantitysupplied q is plotted on the vertical axis, determine the slope-intercept formof the equation of the line which passes through these two points.(ii) Interpret the slope of the equation in this application.(iii) Predict the weekly supply if the market price equals $25 per unit.
Suppose you work for a software company and you would like to estimate the market value of your company. You hypothesize that the market value of a software company (response variable) is a linear function of its earnings (explanatory variable). To test this, you collect data on the earnings and market value of 4 companies in your industry. This results in the following data:
Company
earnings ($mm)
market cap ($mm)
Unicorn
12
70
Bolt

24
PsiCo
100
700
Big
50
450
You fit a linear regression to these data. What is the residual for PsiCo?

The longer a home is on the market, without being sold, the more the price drops. A realtor selects 50 homes that are currently listed for sale. A scatterplot reveals that the association between x = the number of days the home is on the market and y = the current asking price ($) is fairly linear and can be modeled by the equation \hat{y} = 245,000-200xy^=245,000−200x. Additionally, 85.4% of the variation in the current asking price can be explained by this linear model.

- The inventory manager at a warehouse distributor wants to predict inventory cost (Cost in $) based on order quantity (Quantity in units). She thinks it may be a nonlinear relationship because its two primary components move in opposite directions: (1) order processing cost (costs of procurement personnel, shipping, transportation), which decreases as order quantity increases (due to fewer orders needed), and (2) holding cost (costs of capital, facility, warehouse personnel, equipment), which increases as order quantity increases (due to more inventory held). She has collected monthly inventory costs and order quantities for the past 36 months. A portion of the data is shown in the accompanying table. Cost Quantity 54.4 844 52.1 503 60.2 300 53.8 869 51.7 525 57.1 1030 61.1 288 49.8 577 53.9 490 48.2 588 47.5 606 57.4 325 59.6 1160 58.2 1072 58.7 308 58.1 1140 48.4 627 63.4 214 62.5 207 62.5 1174 62.7 1190 61.2 1166 55.9 1067 51.3 655…arrow_forward12. For each of the following, indicate whether it is a positive linear, negative linear, or nonlinear relationship: Quality of performance (Y) increases with increased mental arousal (X) up to an optimal level; then quality of performance decreases with increased arousal.

Each processing line combines various raw materials to produce the same output, Y. One of the processing lines can combine units of input (X) to produce units of output (Y) such that there is a linear relationship between X and Y.

- For the past several years, the state prison system has been concentrating on getting inmates who were high school dropouts help in both earning their GED (an alternative to a high school diploma) and training in trades such as plumbing, carpentry, electrical work, and so on. The state director of prisons has noticed that for participants in the program over the past 9 years, the recidivism rate (in %) has been dropping. She determines that it has a linear relationship, ŷ = 72.12 − 5.03x, where ŷ = predicted recidivism rate and x = number of years the program has been implemented. What recidivism rate (in %) does the director of prisons expect during the 10th year of the program? %arrow_forwardFor the past several years, the state prison system has been concentrating on getting inmates who were high school dropouts help in both earning their GED (an alternative to a high school diploma) and training in trades such as plumbing, carpentry, electrical work, and so on.

Over all 200 eczema cases, however, the old treatment had a higher cure rate than the new treatment- i.e. Simpson's Paradox strikes again.
