Need biostatistics help! Thank you!

Does age affect the standard deviation of the stride distance, measured in centimeters (cm), of Aquarius remigis, the common waterstrider? In a simple random sample of five adult water striders, the standard deviation in stride distance is 1.6927 cm. The sample standard deviation in stride distance among ten randomly selected juvenile striders is 1.2606 cm. Assume that stride distance is normally distributed in each population. Compute an F-statistic to test for equality of two population standard deviations. Report your answer to two decimal places. Compute the numerator degrees of freedom df, of the F-statistic. Report your answer as a whole number. df1 = Compute the denominator degrees of freedom df2 of the F-statistic. Report your answer as a whole number. 10 df 2 = Ortega-Jimenez VM, Rabenau Lv, Dudley R (2017) Data from: Age-dependent effects of water striders moving on perturbed water surfaces.
