Answer...

Here,

I have considered Daily Gross Revenue as the dependent variable and Daily Tour Income and Number of Tourists as the independent variables...

In this case, the Regression Equation is calculated as:

X1 = Daily Tour Income

X2 = Number of Tourists

So.

The regression equation is:

Gross Revenue = 766.981 + 2.977*Daily Tour Income - 12.31*Number of Tourists

Second Part:

Here, I shall consider weekend as a variable... Friday = 1, Saturday = 2 and Sunday = 3..

The data set is is shown below:

The regression output is:

The regression equation is:

Gross Revenue = 1111.8 - 151.22*Weekend + 2.933* Daily Tour Income - 12.04*Number of Tourists

Assume you run a regression on two different models (sets of independent variables). The first model results in an ?2R2 of 0.60 and the second model results in an ?2R2 of 0.64. This would mean that Select one: a. The independent variables in the first model are not statistically significant, despite what the t-stats and p-values suggest. b. The second model has better overall explanatory power, but a better ?2R2 is only gained at the expense of other factors. The...
