I keep getting the wrong answer. The formula is x=(means) + (z)(o)

2310+580.9(0.09)=2362

The answer keeps coming back incorrect. I'm not sure what i'm doing wrong

 

**Per Capita Energy Consumption Analysis**

The per capita energy consumption level (measured in kilowatt-hours) in a specific country for a recent year can be modeled by a normal distribution, illustrated by the figure provided.

**Questions:**

(a) What consumption level represents the 9th percentile?
(b) What consumption level represents the 18th percentile?
(c) What consumption level represents the third quartile?

**Graph Explanation:**

The graph depicts a normal distribution curve of energy consumption in kilowatt-hours. Key parameters of the distribution are provided:
- The mean (μ) is 2310 kWh.
- The standard deviation (σ) is 580.9 kWh.

The x-axis represents kilowatt-hours, ranging from 310 to 4310 kWh. Vertical lines indicate significant points in the distribution.

**Solution Section:**

(a) The consumption level that represents the 9th percentile is _______ kilowatt-hours. 
(Round to the nearest integer as needed.)
