Because the confidence interval contains the critical value, there appears to be a significant difference between the two proportions. because the confidence interval consists ▼ ▼ the critical value, the significance level, 0, the pooled sample proportion, it appears that the first proportion is ▼ not significantly different from less than greater than the second proportion. there is ▼ insufficient sufficient evidence to support the claim that the rate of polio is less for children given the vaccine than it is for children given a placebo.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
