-
The problem involves a reported color distribution for a candy, with the following color percentages:
- Green: 17%
- Orange: 19%
- Yellow: 15%
- Blue: 23%
-
The observed frequencies (number of candies for each color) are given as:
- Green: 18
- Orange: 28
- Yellow: 9
- Blue: 17
The question is asking you to determine the null and alternative hypotheses and to compute the test statistic (χ²) for the goodness-of-fit test.
Null and Alternative Hypotheses:
- Null Hypothesis (H₀): The color distribution is the same as that reported.
- Alternative Hypothesis (H₁): The color distribution is different from that reported.
Next Steps:
- Expected frequencies: The expected frequency for each color is calculated by multiplying the total number of candies by the reported percentage.
- Chi-Square test statistic (χ²): We calculate the test statistic using the formula:
Where:
- is the observed frequency.
- is the expected frequency.
