User: A test is conducted in eight cities to see if giving away free transit system maps will increase bus ridership. In a regression analysis, the dependent variable is the increase in bus ridership in thousands of persons from the start of the test until its conclusion. The independent variables are X1 = the number in thousands of free maps distributed and X2 = a binary equal to 1, if the city has free downtown parking and 0 otherwise. The estimated regression equation is Y = 1.32+.0345X1-1.45X2. If the Y value for city 3 is 7.3, X1 = 140, and X2 = 0 the residual for city 3 in thousands is:

Weegy: The estimated regression equation for Y should be Y = 1.32+.0345X1-1.45X2. There is error in your given equation. And the answer for that equation will be 1.15

User: What parametric test is equivalent to the nonparametric Spearman's rank test?

Weegy: Parametric statistical tests assume that your data are normally distributed (follow a classic bell-shaped curve). An example of a parametric statistical test is the Student's t-test. Non-parametric tests make no such assumption. [ An example of a non-parametric statistical test is the Sign Test. .............. ]
