Final answer:
The number closest to 7 among the valid F statistics is 7.28.
Step-by-step explanation:
The question regarding which of the numbers is closest to 7 pertains to basic numerical comparison. None of the provided options in the new question (A. 47, B. 46, C. 50, D. 51) is close to 7 in value. However, if we refer to the original question provided for context, which lists a series of F statistics numbers: A. 2.47, B. 5.95, C. -3.61, D. 7.28, E. 0.97, we can determine which is closest to 7. F statistics are always non-negative, as they are a ratio of variances, which cannot be negative. Hence, we would disregard any negative value like -3.61. Therefore, the choice that is closest to 7 among the valid F statistics would be D. 7.28.
