According to the exhibit sleep time statement option A is the most suitable answer because p-value is less than coefficient of determination. Therefor null hypothesis rejected.
Variation can be defined as any difference between the individuals in a species or groups of organisms of any species. mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and gene flow contribute to it as well.
Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation.

The complete question is-
Refer to Exhibit Sleep Time.
Think about testing the significance of the coefficient of determination. Which one of the following statements is correct using α = 0.10?
A. Because the p-value for F-statistic is 0.065, we can reject the null hypothesis that the population coefficient of determination is less than or equal to zero and conclude that the independent variable age explains a non-zero percentage of variation in the sleep hours in the population.
B. Because R2 is close to zero, we can conclude that the there is no relationship between the age and the sleep hours in the population.
C. Because R2 is different from zero, we can conclude that the independent variable age explains a non-zero percentage of variation in the sleep hours in the population.
D. Because R2 is close to zero, we can conclude that the independent variable age explains 0% of variation in the sleep hours in the population.
