I am having difficulty with The Analysis of Biological Data chapter 10 question 15AP, I need to check my solutions but there are none posted for me to review. If I could compare answers that would be great.

### Understanding Temperature Distributions in Extreme Climates

**Problem Context:**
The highest recorded temperature during the month of July for a given year in Death Valley, California, follows approximately a normal distribution. This distribution has a mean of 123.8°F and a standard deviation of 3.1°F, according to Weather Source (2009).

**Analysis Questions:**

**a. Probability of Temperatures Below 120°F:**
- What is the probability for a given year that the temperature never exceeds 120°F in July in Death Valley?

**b. Probability of Temperatures Above 128°F:**
- What is the probability that the temperature in Death Valley exceeds 128°F during July in a randomly chosen year?

**Exercise: Sketching Distributions**

**16. Drawing a Normal Distribution:**
- Draw a distribution that is approximately normal, with a mean equal to 10 cm and variance equal to 360.
- On the same graph, draw the distribution of the means of samples taken from individuals.

---

**Diagrams and Graphs Explanation:**

The diagram would typically illustrate a bell curve representing a normal distribution. This graph will show the mean temperature as the peak of the curve at 123.8°F, with the spread determined by the standard deviation of 3.1°F.

For problem 16, the graph should depict:
- A normal distribution with a mean (central peak) labeled at 10 cm.
- The variance is shown in the spread of the curve (360).
- An overlay or separate line illustrating sample means, typically with a narrower spread if based on the Central Limit Theorem and assuming large samples.

These visual aids help understand how temperatures fluctuate in extreme conditions and concepts of probability related to normal distributions.
