4. Fill in the following contingency table with the number of observations that fall into each com- bination of categories. For example, if there are 100 overall pieces of orange colored Skittles, you would enter 100 into the first cell. Outcome Not Orange (x) 49 83 I l62 Orange Row Totals Skittles (S) M&M's (M) 150 100 250 Candy 17 88 Column Totals 5. Compute the point estimate for the difference in the proportion of orange colored pieces between the two brands.

**Combining Data for Analysis**

In this section, we will aggregate your data with that of the class. Below is a table organized by observation number for candy samples. Each entry lists the observation number, type of candy, number of orange candies, and total number of pieces.

| Observation (Bag) | Type of Candy | No. of Orange | Total No. of Pieces |
|-------------------|---------------|---------------|---------------------|
| 1                 |               |               |                     |
| 2                 |               |               |                     |
| 3                 |               |               |                     |
| 4                 |               |               |                     |
| 5                 |               |               |                     |
| ...               |               |               |                     |
| 36                |               |               |                     |

(Note: The table from the image is currently unfilled and requires data input.)

**Contingency Table**

Next, fill in the following contingency table with observations distributed into different categories. For instance, if there are 100 pieces of orange-colored Skittles, input the number 100 into the appropriate cell.

| Candy       | Outcome     | Row Totals |
|-------------|-------------|------------|
|             | Orange      | Not Orange |
| Skittles (S)| 71          | 79         | 150        |
| M&M's (M)   | 17          | 83         | 100        |
| Column Totals| 88         | 162        | 250        |

**Point Estimate Calculation**

Finally, compute the point estimate for the difference in the proportion of orange-colored pieces between Skittles and M&M's. Use the data from the contingency table to determine this difference.

### Statistical Analysis Exercises

**6. Using the data from the contingency table, obtain the value of the test statistic of our test.**

**7. Calculate the p-value of the test.**

**8. Interpret the p-value.**

**9. State the conclusions of the test in the terms of the problem.**

**10. Based on the hypothesis test alone, do you expect the value 0 to be in a 95% confidence interval for the difference in population proportion of orange colored candies \((p_1 - p_2)\) between the two brands? Explain without computing the interval.**

---

These exercises guide students through key steps in statistical hypothesis testing, focusing on calculations and interpretation of the p-value and drawing conclusions based on statistical evidence.
