Question
A particular lake is known to be one of the best places to catch a certain type of fish. In this table, \( x \) represents the number of fish caught in a 6-hour period while fishing from shore. The percentage data reflects the proportions of fishermen who caught \( x \) fish in this time frame.

| \( x \)         | 0   | 1   | 2   | 3   | 4 or more |
|-----------------|-----|-----|-----|-----|-----------|
| \%              | 43% | 35% | 15% | 6%  | 1%        |

(a) Convert the percentages to probabilities and create a histogram of the probability distribution. (Select the correct graph.)

**Explanation:** 

To convert the percentages to probabilities, divide each percentage by 100. The probabilities for catching \( x \) fish in a 6-hour period are:

- Probability of catching 0 fish: 0.43
- Probability of catching 1 fish: 0.35
- Probability of catching 2 fish: 0.15
- Probability of catching 3 fish: 0.06
- Probability of catching 4 or more fish: 0.01

**Histogram Description:**

The histogram should have the number of fish caught (\( x \)) on the x-axis and the probability on the y-axis. Each bar represents the probability of catching a specific number of fish:

- The first bar (0 fish) reaches up to 0.43.
- The second bar (1 fish) reaches up to 0.35.
- The third bar (2 fish) reaches up to 0.15.
- The fourth bar (3 fish) reaches up to 0.06.
- The last bar (4 or more fish) reaches up to 0.01.

The histogram provides a visual representation of the probability distribution of catching fish in a 6-hour period.

(d) Compute μ, the expected value of the number of fish caught per fisherman in a 6-hour period (round 4 or more to 4). (Enter a number. Round your answer to two decimal places.)

μ = [___] fish

(e) Compute σ, the standard deviation of the number of fish caught per fisherman in a 6-hour period (round 4 or more to 4). (Enter a number. Round your answer to three decimal places.)
