Example B The equation z(k+1, l) = 42(k, l+ 1) (5.84) leads to the conclusion that A = 4µ. Therefore, equation (5.84) has the special solutions 2(k, l) = 4*µk+e. (5.85) Summing expressions of this form allows the conclusion z(k, l) = 4* f(k + l), (5.86) where f is an arbitrary function of k + l. The separation-of-variables method, where zp(k, l) = CkDe, gives Ck+1De = 4CkDe+1; (5.87) which can be written in either of the forms Ck+1 De+1 Ck+1 or 4De+1 = a. (5.88) 4С = a De Ck De The respective solutions to these equations give z(k, l) = 4*ak+l or z(k, l) = 4-ak+e. (5.89) Summing over a allows us to obtain the general solution z(k, l) = 4* f (k + l) or z(k,l) = 4 g(k, l), (5.90) where f and g are arbitrary functions of k + l.

Suppose that n observations are chosen at random from a continuous pdf fY(y). What is the probability that the last observation recorded will be the smallest number in the sample? I asked this question earlier today, but didn't quite understand all of the response. P(y1<=yn)p(y2<=yn) and so on was used, but shouldn't the yn be listed first in the inequality since we want to know if yn is the smallest?

A physician wants to test if temperature has an effect on heart rate. In order to do this, she compares the heart rate in beats per minute of several random volunteers after a period of time in a room with a temperature of 50∘F and after a period of time in a room with a temperature of 75∘F. Suppose that data were collected for a random sample of 11 volunteers, where each difference is calculated by subtracting the heart rate in beats per minute in the 50∘F room from the heart rate in beats per minute in the 75∘F room. Assume that the populations are normally distributed. The test statistic is t≈5.627, α=0.05, the corresponding rejection regions are t<−2.228 and t>2.228, the null hypothesis is H0:μd=0, and the alternative hypothesis is Ha:μd≠0.
