Applied to focusing lenses and mirrors, including telescopes, binoculars, and cameras, the focal ratio or 'F-number' is (the focal length of the lens or mirror) divided by (its aperture or diameter)

A F-ratio test compares 2 variances and tell if they are significantly different. A Chi-square test compares count data.
lets see...lets apply a simple ratio... (56/f) = (64/100) 64(f) = 5600 87.5 = f = your answer O.O
When the second element of the ratio is 1.
the numerator of the F-ratio
It is the ratio of physical characteristics of parents and the potential offspring traits. It is the ratio of physical characteristics of parents and the potential offspring traits.
Computing F-ratioThe F-ratio is used to determine whether the variances in two independent samples are equal. If the F-ratio is not statistically significant, you may assume there is homogeneity of variance and employ the standard t-test for the difference of means. If the F-ratio is statistically significant, use an alternative t-test computation such as the Cochran and Cox method.

In general the distribution of F-ratio means what
The F-ratio is a statistical ratio which arises as the ratio of two chi-square distributions.If X and Y are two random variables which are independent and approximately normally distributed, then their variances have chi-squared distributions. The ration of these chi-square distributions, appropriately scaled, is called the F-ratio.The F-ratio is used extensively in analysis of variance to determine what proportion of the variation in the dependent variable is explained by an explanatory variable (and the model being tested).
The ratio of red to white phenotypic characteristics is approximately 93:36, which simplifies to 31:12 when divided by their greatest common factor of 3.
no.
That is dependant on the ratio of the differential. The ratio is usually selected by the automotive engineer who is calculating the performance requirements and engine displacement/torque along with maximum and nominal engine RPM. It can be as low as 1800 RPM and depending on the engine characteristics, the engineer could have determined that it should be 3500 RPM or more.
