The data given to the right includes data from 42 candies, and 10 of them are red. The company that makes the candy claims that 30% of its candies are red. Use the sample data to construct a 95% confidence interval estimate of the percentage of red candies. What do you conclude about the claim of 30%? Construct a 95% confidence interval estimate of the population percentage of candies that are red. %

**Educational Text: Confidence Interval for Red Candies**

The data given includes information from a sample of 42 candies, of which 10 are red. The candy company claims that 30% of its candies are red. Using this sample data, construct a 95% confidence interval estimate for the percentage of red candies. Analyze the confidence interval to determine whether it supports the company's claim of 30%.

**Constructing the Confidence Interval:**

To calculate the 95% confidence interval for the population percentage of red candies, follow these steps:

1. **Proportion of Red Candies in Sample:**
   - Sample Proportion (\( \hat{p} \)) = Number of Red Candies / Total Candies = 10/42 

2. **Calculation of Confidence Interval:**
   - Use standard formulas for a confidence interval for a proportion.

3. **Interval Estimate:**
   - \( \_\_\_\_ \% < p < \_\_\_\_ \% \)

*Insert the values in the blanks with integers or decimals rounded to one decimal place as needed.*

**Weights of a Sample Bag of Candy:**

The table below shows the weights (in grams) of candies grouped by color:

| Red  | Blue | Brown | Green | Yellow |
|------|------|-------|-------|--------|
| 0.879 | 0.949 | 0.925 | 0.882 | 0.888 |
| 0.932 | 0.825 | 0.704 | 0.884 | 0.745 |
| 0.831 | 0.706 | 0.817 | 0.815 | 0.718 |
| 0.709 | 0.928 | 0.912 | 0.863 | 0.765 |
| 0.954 | 0.716 | 0.885 | 0.868 | 0.964 |
| 0.758 | 0.734 | 0.925 | 0.927 | -    |
| 0.928 | 0.705 | 0.816 | 0.712 | -    |
| 0.933 | 0.985 | -    | 0.785 | -    |
| 0.894 | 0.971 | -    | 0.805 | -    |
