The population, P, of bacteria in a culture can be calculated at any time, t, using the equation P = a(2). In the equation, the initial number of bacteria is a. The initial number of bacteria in two different cultures were 100 and 125.

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

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.
