Question
Transcribed Image Text:In a study by Dr. Harold J. Morowitz of Yale University, data were gathered that showed the
relationship between the death rate of men and the average number of hours per day that the
men slept. These data are listed in the following table:
7 8. 9
f (x) 1121
805
626
813 967
(Source: Morowitz, Harold J., "Hiding in the Hammond Report,
Hospital Practice.)
Here x is average number of hours of sleep, and f(x) the death rate per 100 000 males.
a) Construct a backward difference table for the data.
b) Use the backward difference table presented in a), along with Newton's backward difference
formula, to approximate f(10) with a polynomial of degree 3, P3(x). Start with n=9.
