This is the second part of a three-part problem. consider the system of differential equations y′1y′2==7y1+2y2,−4y1+y2. verify that for any constants c1 and c2, the functions y1(t)y2(t)==c1e5t+c2e3t,−c1e5t−2c2e 3t, satisfy the system of differential equations. enter c1 as c1 and c2 as c2. find the value of each term in the equation y′1=7y1+2y2 in terms of the variable t. (enter the terms in the order given.) equation editorequation editor = equation editorequation editor + equation editorequation editor . find the value of each term in the equation y′2=−4y1+y2 in terms of the variable t. (enter the terms in the order given.) equation editorequation editor = equation editorequation editor + equation editorequation editor .

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
