Definition 7.1.1 laplace transform let f be a function defined for t ≥ 0. then the integral ℒ{f(t)} = ∞ e−stf(t) dt 0 is said to be the laplace transform of f, provided that the integral converges. find ℒ{f(t)}. ℒ{f(t)} = −e−s+1 s2 (s > 0)

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
