The variable April takes value 1 if the recorded cases are from April 2020, and takes value 0 if the recorded cases are from March 2020. The variable lockdown takes value 1 if the state put in place a Stay-at-home order beginning from March 2020, and takes value 0 otherwise.

After participants taste each brand, the first researcher simply checks to see if participants can distinguish them reliably by labeling each cola as "same" or "different" from the others, by giving them the same or different letter or number code. The second researcher asks each participant to identify the most preferred, the second most preferred, and the least preferred. The third researcher asks each participant to rate each of the colas on a 10-point scale, where a rating of 1 indicates “terrible taste” and 10 indicates “excellent taste," with the assumption that the difference betweeen a rating of 4 and 6 is the same as the difference between a 6 and 8.

- Sherwin-Williams Company is attempting to develop a demand model for its line of exterior house paints. The company’s chief economist feels that the most important variable affecting paint sales (Q) (measured in gallons) is the Selling price (P) (measured in Ghana cedis per gallon). The chief economist decides to collect data on the variables in a sample of 10 company sales regions that are roughly equal in population. Data on paint sales, and selling prices were obtained from the company’s marketing department. The data are shown in the table below: Sherwin-Williams Company Data Sales Region Sales (Q) Selling Price (P) (GHS/Gallon) 1 160 15 2 220 13.5 3 140 16.5 4 190 14.5 5 130 17 6 160 16 7 200 13 8 150 18 9 210 12 10 190 15.5 Specify the linear demand model for Sherwin-William’s paint.

In deciding by what amount to reduce total subsidies, experiments were carried out for determining the possible reduction in exports, mainly to the United States, that would result from the subsidy reduction. Over a small range of values, economists wanted to test whether there is a positive correlation between level of subsidy and level of exports. A computer simulation of the economic variables involved in the pasta exports market was carried out. The results follow. Assuming that the simulation is an accurate description of reality and that the values obtained may be viewed as a random sample of the populations of possible outcomes, state whether you believe that a positive rank correlation exists between subsidy level and exports level over the short range of values studied Qarrow_forwardThe following are some of the options available when it comes to data collection: Include a concise explanation of the method's intended outcome, as well as any potential advantages or disadvantages it may have. conversations with a number of individualsarrow_forward
