**Title: Understanding the Relationship Between TV Appearances and Guitar Demand**

**Introduction:**

Mark Gershon, owner of a musical instrument distributorship, theorizes that the demand for guitars might be influenced by the number of television appearances by the popular group Maroon 5 during the previous month. He has collected the following data:

**Data Table:**

| **Maroon 5 TV Appearances** | 4 | 5 | 6 | 6 | 9 | 5 |
|----------------------------|---|---|---|---|---|---|
| **Demand for Guitars**      | 2 | 5 | 6 | 4 | 10 | 7 |

*Note:* This exercise includes only parts b, c, and d of the analysis.

**Exercise:**

b) **Using the Least-Squares Regression Method:**

The task is to use the least-squares regression method to forecast the demand for guitars. The equation for forecasting is represented as:

\[ Y = \text{[Enter calculated intercept]} + \text{[Enter calculated slope]} \times X \]

*Instructions:* Round your responses to four decimal places.

**Explanation of Approach:**

In this exercise, learners are required to utilize the given data to perform a least-squares regression analysis, which is a statistical technique used to determine a line of best fit and make predictions based on linear data relationships. The calculated equation will allow predictions of guitar demand based on the number of Maroon 5's TV appearances.
