**Question:**
Which of the following conclusions is correct for these test results?

**Test Details:**
- Command: `bartlett.test(len~river, data=rivers)`
- Test: Bartlett test of homogeneity of variances
- Data: Length by river
- Results:
  - Bartlett's K-squared = 0.61394
  - Degrees of freedom (df) = 4
  - p-value = 0.5226

*Hint:* The first line of code should tell you the type of test you are dealing with.

**Options:**
1. ○ There is NO significant difference in variances among the rivers.
2. ○ There is a significant difference in variances among the rivers.
3. ○ There is NO significant difference in means among the rivers.

**Explanation:**
This involves a Bartlett test, which is used to test if multiple samples have equal variances. A p-value greater than the common significance level (e.g., 0.05) indicates that there is no significant difference in variances. Thus, option 1 is correct.
