#### Q.1. For the given data, determine the R-squared value for the given data

Data:

Miles travel (independent variable) Petrol Consumption in litre (dependent variable)

20 1

45 3

56 5

34 2

28 1.6

49 3.7

- 0.887
**0.956**- 0.945
- 0.932

#### Q.2. With reference to the data given in question no. 1, test the null hypothesis: “There is no significant relationship between the variables”. we will:

#### Q.3. State TRUE or FALSE, in context to regression analysis –

Statement: “The variance of error, is same for all values of the independent variable”

**True**- False

#### Q.4. A regression analysis between sales (Y in $1000) and advertising (X in dollars) resulted in the following equation

Y = 30,000 + 5 X

The above equation implies that an:

- increase of $5 in advertising is associated with an increase of $5,000 in sales
- increase of $1 in advertising is associated with an increase of $5 in sales
- increase of $1 in advertising is associated with an increase of $35,000 in sales
**increase of $1 in advertising is associated with an increase of $5,000 in sales**

#### Q.5.** **In a regression and correlation analysis if r2 = 1, then Sum of square of Error (SSE)

- SSE must also be equal to one
**SSE must be equal to zero**- SSE can be any positive value
- SSE must be negative

#### Q.6. In a regression analysis if Sum of square of Error (SSE) = 200 and Sum of square of Regression (SSR) = 300, then the coefficient of determination is

- 0.6667
- 0.4000
**0.6000**- 1.5000

#### Q.7. Regression analysis was applied between demand for a product (Y) and the price of the product (X), and the following estimated regression equation was obtained.

Y = 120 – 10 X

Based on the above estimated regression equation, if price is increased by 2 units, then demand is expected to

#### Q.8. Regression analysis was applied between sales (Y in $1,000) and advertising (X in $100), and the following estimated regression equation was obtained.

Y = 80 + 6.2 X

Based on the above estimated regression line, if advertising is $10,000, then the point estimate for sales (in dollars) is

- $62,080
- $142,000
- $700
**$700,000**

#### Q.9. In regression analysis if the dependent variable is measured in dollars, the independent variable

#### Q.10.** **If the coefficient of correlation is 0.90, then the coefficient of determination
