a) In a regression, if you have used a variable which is in the form of a dummy variable (0= not white, 1= white) such as; lnw= alpha + beta white + u, does the regression in excel also show the value of non white? If so, how?

b) Also, is an r squared value of 0.19 considered good or not? What does it mean?

Plese provide easy to understand and clear answers which perfectly answer the question only.

Regression: First, choose any metric variable as the dependent variable and then choose any three other metric variables as independent variables. HOWEVER, this process must be repeated until you find a model that produces a significant F-calc (p-value (sig) <.05). Thus, you may have to sort through several combinations of dependent and independent variables before finding a combination that produces a significant F-calc. This is actually quite easy to do in SPSS using the drop down menus as shown in...

Aluminum wires exposed to air form a layer of insulating Al2O3, through which electrons have to tunnel to get through an interconnect. A simple model of electrons tunneling through an Al2O3 barrier of thickness L between two Al wires implies the following: for small fixed voltage V, the current I is Ce^(-2KL), where C and K are constants. In other words, the resistance R=V/I increases proportional to e^(2KL). Solving the Schrödinger equation gives K=sqrt(2mU/ 2 ) where m is the...

The data below were obtained to predict the sound frequency to which a person’s ear will respond based upon the length of time a person has been exposed to a high level of noise. Here “length of exposure” is the amount of time in weeks that a person has been living close to a major airport and the “hearing range” is reported in thousand cycles per second. Length of exposure In weeks (Left) Hearing range In thousand cycles per second...
