Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 6.3 parts/million (ppm). A researcher believes that the current ozone level is at an insufficient level. The mean of 960 samples is 6.2 ppm. Assume the standard deviation is known to be 1.1.

Question
**Title: Evaluating Ozone Levels in the Upper Atmosphere**

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 6.3 parts per million (ppm). A researcher believes that the current ozone level is at an insufficient level. The mean of 960 samples is 6.2 ppm. Assume the standard deviation is known to be 1.1. Does the data support the claim at the 0.1 level?

**Step 1 of 5: Enter the Hypotheses**

- **Null Hypothesis (H₀):** 
  - [Enter your hypothesis here]
  
- **Alternative Hypothesis (Hₐ):**
  - [Enter your hypothesis here]

**Answer:** 2 Points

**Graphical Elements:**
This exercise requires filling in values for the null and alternative hypotheses based on the given data and research question. There are no diagrams or graphs provided in this step, but the task focuses on forming the hypotheses necessary for a statistical test.
