A garage sells three types of fuel: unleaded petrol, diesel and
tractor diesel. The probability that a randomly selected customer
will buy a particular fuel is shown in the table:
Fuel Probability
Unleaded 0.40
Diesel 0.45
Tractor Diesel 0.15
1. Find the probability that of two randomly selected customers:
(i) Both will buy diesel (ii) Exactly one will buy diesel 2. Find
the probability that of three randomly selected customers: (i) All
will buy unleaded (ii) Exactly two will buy diesel (ii) One will
buy tractor diesel, one will buy unleaded and one will buy
diesel
2. A mechanical device has a wearout time distributed normally with a mean of 1100 hours and a standard deviation of 50 hours. Find the values that constitute the central 95% of the wearout times.

The effect of three different lubricating oils on fuel
economy in diesel truck engines is being studied. Fuel economy is
measured using brake-specific fuel consumption after the engine has
been running for 15 minutes. Five different truck engines are
available for the study, and the experimenters conduct the
following randomized complete block design.

An experiment reported in Popular Science compared fuel economies for two types of similarly equipped diesel mini-trucks.
An experiment reported in Popular Science compared fuel economies for two types of similarly equipped diesel mini-trucks. Let us suppose that 12 Volkswagen and 10 Toyota trucks were tested in 90- kilometer-per-hour steady-paced trials. If the 12 Volkswagen trucks averaged 16 kilometers per liter with a standard deviation of 1.0 kilometer per liter and the 10 Toyota trucks averaged 11 kilometers per liter with a standard deviation of 0.8 kilometer per liter, construct a 90% confidence interval for the difference...
