The bigger the stop sign, the more expensive it is. Here is a graph of the height of a sign in inches versus its cost in dollars. 1. Describe why performing linear regression with these data is not a good decision. To achieve linearity, the data was transformed using a square root function of cost. Here are the results and a residual plot. Dependent Variable: sqrt(cost) R (correlation coefficient) = 0.98946627 R-sq = 0.97904349 s: 0.2141 2. Do you think this transformation for linearity was successful? Why? 3. Write the transformed regression equation. Make sure to define any variables used in your equation. 4. Interpret R-sq in the context of this problem. 5. Use your equation to predict the cost of a 48" stop sign. Parameter coeff se Intercept 1.1857 0.4346 height 0.1792 0.0151

Asapembassies differ from consulates in thata) compared to a consulate, an embassy is a smaller representation of a nation's government in a foreign country. b) consulates are permanent diplomatic missions generally located in a country’s capital, whereas a country may have a number of embassies in various cities. c) embassies are permanent diplomatic missions generally located in a country’s capital, whereas a country may have a number of consulates in various cities. d) embassies deal solely with economic diplomacy and trade relations, whereas consulates deal primarily with political and diplomatic relations with the host nation. e) countries establish embassies in another nation only if it recognizes the sovereignty of that country, whereas consulates exist without regard to recognition of a nation's sovereignty.
