A fly hits a 20000 kg vehicle. a. Which of the masses, the fly or the vehicle, experiences the greater force?
the fly because it hit something that is 2000kg
b. If the fly experienced a force of 100 N when it hits, how big was the force on the
vehicle in this collision?

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
