### Analyzing Birth Frequencies Throughout the Week: A Statistical Approach

Randomly selected birth records were obtained and categorized as listed in the table presented below. Using a 0.01 significance level, we will test the reasonable claim that births occur with equal frequency on different days of the week. Consider the apparent lower frequencies on Saturday and Sunday, and how they might be explained.

#### Table of Births by Day of the Week

| Day  | Number of Births |
|------|------------------|
| Sun  | 40               |
| Mon  | 55               |
| Tues | 63               |
| Wed  | 56               |
| Thurs| 65               |
| Fri  | 59               |
| Sat  | 49               |

### Statistical Analysis Steps

**1. Determine the null and alternative hypotheses.**

- \( H_0 \): 
- \( H_1 \): 

**2. Calculate the test statistic, \( \chi^2 \).**

\[ \chi^2 = \text{(Round to three decimal places as needed.)} \]

**3. Calculate the P-value.**

\[ \text{P-value} = \text{(Round to four decimal places as needed.)} \]

**4. What is the conclusion for this hypothesis test?**

- \( \chi^2 \) value calculation and interpretation.
- Decision on null hypothesis based on the P-value.

### Conclusion Options

- **A.** Reject \( H_0 \). There is insufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week. 
- **B.** Fail to reject \( H_0 \). There is insufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
- **C.** Fail to reject \( H_0 \). There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.
- **D.** Reject \( H_0 \). There is sufficient evidence to warrant rejection of the claim that births occur with equal frequency on the different days of the week.

**5. How might the apparent lower frequencies on Saturday and Sunday be explained?**

- **A.** Induced or Caesarean-section births are scheduled on weekends whenever possible.
- **B.** Induced or Caesarean-section births are scheduled
