Sample 2012 MNB1601 Exam Question and Its Step-by-Step Solution

To illustrate the approach, here is a representative question from the 2012 paper along with a comprehensive solution:

Question:

"Given the dataset below, perform a linear regression analysis to determine the relationship between variable X and variable Y. Interpret the coefficients and discuss the significance of the model."

| X | Y |

|---|---|

| 2 | 5 |

| 4 | 9 |

| 6 | 13 |

| 8 | 17 |

| 10 | 21 |

Solution:

Step 1: Plot the Data

• Plot X against Y to visualize the relationship.
• Observation: The points suggest a straight-line relationship.

Step 2: Calculate Means

• \( \bar{X} = \frac{2 + 4 + 6 + 8 + 10}{5} = 6 \)
• \( \bar{Y} = \frac{5 + 9 + 13 + 17 + 21}{5} = 13 \)

Step 3: Compute the Slope (b1)

\[

b_1 = \frac{\sum (X_i - \bar{X})(Y_i - \bar{Y})}{\sum (X_i - \bar{X})^2}

\]

Calculations:

• Numerator:

\[

(2-6)(5-13) + (4-6)(9-13) + (6-6)(13-13) + (8-6)(17-13) + (10-6)(21-13)

\]

\[

= (-4)(-8) + (-2)(-4) + (0)(0) + (2)(4) + (4)(8) = 32 + 8 + 0 + 8 + 32 = 80

\]

• Denominator:

\[

(2-6)^2 + (4-6)^2 + (6-6)^2 + (8-6)^2 + (10-6)^2 = 16 + 4 + 0 + 4 + 16 = 40

\]

• Slope:

\[

b_1 = \frac{80}{40} = 2

\]

Step 4: Calculate Intercept (b0)

\[

b_0 = \bar{Y} - b_1 \bar{X} = 13 - 2 \times 6 = 13 - 12 = 1

\]

Step 5: Write the Regression Equation

\[

Y = b_0 + b_1 X = 1 + 2X

\]

Step 6: Interpret the Coefficients

• The intercept (1) indicates that when X=0, Y is expected to be 1.
• The slope (2) suggests that for each unit increase in X, Y increases by 2 units.

Step 7: Significance and Model Evaluation

• The perfect linear pattern in the dataset indicates a strong relationship.
• In real scenarios, perform statistical tests (like t-tests for coefficients) to assess significance.
• Check R-squared value for model fit; here, it would be 1, indicating a perfect fit.

Conclusion:

The linear regression analysis shows a strong positive relationship between X and Y, with the model Y=1+2X effectively predicting Y based on X.
