The data presented in Part D shows the results of artificial selection for hairy Wisconsin Fast Plants. Identify the null hypothesis for this investigation? A. If the mean number of trichomes is greater in the second generation than in the parent population, then selection has occurred.B. There will be no difference between the mean number of trichomes in the second generation compared to the parent population.C. As a result of selection, the mean number of trichomes will be greater in the second generation.D. If plants with the most trichomes in the first generation are selected as parents, then the second generation will have more trichomes. ### Trichome Number Analysis in Plant PopulationsThe image consists of two bar graphs that compare the distribution of trichome numbers in a parent plant population and its second generation.#### Parent Population- **Title:** Parent population- **X-Axis:** Trichome number (categories: 0, 1-5, 6-10, 11-15, 16-20, 21-25, 26-30, 31-35)- **Y-Axis:** Number of plants- **Description:** The graph shows that the majority of the parent population has trichomes in the range of 6-15, with the highest frequency in the 6-10 and 11-15 categories. The number of plants decreases as the trichome number increases beyond 15.#### Second Generation- **Title:** Second generation- **X-Axis:** Trichome number (categories: 0, 1-5, 6-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, 41-45)- **Y-Axis:** Number of plants- **Description:** The second generation shows a shift towards higher trichome numbers, peaking in the 16-20 category. The distribution is broader compared to the parent population, with an extended range up to 41-45 trichomes, although with fewer plants at these higher numbers.These graphs illustrate the genetic variation and potential adaptation in plant populations over generations.

In statistics, Null Hypothesis is defined as the general statement or commonly accepted fact or default value or universal truth that states that there is no difference between the two sample measures. Null Hypothesis of this investigation would be There will be no difference between the mean number of trichomes in the second generation compared to the parent population.

Question

The data presented in Part D shows the results of artificial selection for hairy Wisconsin Fast Plants. Identify the null hypothesis for this investigation?

A. If the mean number of trichomes is greater in the second generation than in the parent population, then selection has occurred.

B. There will be no difference between the mean number of trichomes in the second generation compared to the parent population.

C. As a result of selection, the mean number of trichomes will be greater in the second generation.

D. If plants with the most trichomes in the first generation are selected as parents, then the second generation will have more trichomes.

### Trichome Number Analysis in Plant Populations

The image consists of two bar graphs that compare the distribution of trichome numbers in a parent plant population and its second generation.

#### Parent Population

- **Title:** Parent population
- **X-Axis:** Trichome number (categories: 0, 1-5, 6-10, 11-15, 16-20, 21-25, 26-30, 31-35)
- **Y-Axis:** Number of plants
- **Description:** The graph shows that the majority of the parent population has trichomes in the range of 6-15, with the highest frequency in the 6-10 and 11-15 categories. The number of plants decreases as the trichome number increases beyond 15.

#### Second Generation

- **Title:** Second generation
- **X-Axis:** Trichome number (categories: 0, 1-5, 6-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, 41-45)
- **Y-Axis:** Number of plants
- **Description:** The second generation shows a shift towards higher trichome numbers, peaking in the 16-20 category. The distribution is broader compared to the parent population, with an extended range up to 41-45 trichomes, although with fewer plants at these higher numbers.

These graphs illustrate the genetic variation and potential adaptation in plant populations over generations.
