Textbook Question
Chapter 24, Problem 47P
Referring to the data from Problem 20.61, find the strain rate using finite difference methods. Use second-order accurate derivative approximations and plot your results. Looking at the graph, it is apparent that there is some experimental startup error. Find the mean and standard deviation of the strainrate after eliminating the data points representing the experimental startup error.

(d) What proportion of the observed variation in efficiency ratio can be attributed to the simple linear regression relationship between the two variables?
The proportion of the observed variation in efficiency ratio which can be attributed to the simple linear regression relationship is equal to the coefficient of determination, r².
r² = 1-
SSE
SST'
where SSE = Syy - B₁Sxy, and SST = Syy.
First, use v² = 77.1001, (v₁)² = (40.17)² = 1,613.6289, and n = 24 to calculate Sy

There are no other breeds of cows in the field. The contagion spreads through contact. Cows without spots that come in to contact with cows with spots immediately develop spots. Assume that during the modeling period the effects are immediate and permanent (spotted cows remain spotted). It is reasonable to assume that the rate at which cows develop spots is proportional to the product of the number of spotted cows and the number of non-spotted cows. Let S = S(t) be the number of spotted cows at time t. Write a differential equation reflecting the situation.arrow_forwardQuestion1.
