A study of the relationship between age and various visual functions (such as acuity and depth perception) reported the following observations on area of scleral lamina (mm2) from human optic nerve heads ( Morphometry of Nerve Fiber Bundle Pores in the Optic Nerve Head of the Human, Experiment. Eye Res., 1988: 559—568):
2.75 2.62 2.74 3.85 2.34 2.74 3.93 4.21 3.88
4.33 3.46 4.52 2.43 3.65 2.78 3.56 3.01
c. If the two largest sample values, 4.33 and 4.52, had instead been 5.33 and 5.52, how would this affectf f^s? Explain.
d. By how much could the observation 2.34 be increased without affecting f^s? Explain.
e. If an 18th observation, x18 =4.60, is added to the sample, what is f^s
