The weight of a car can influence the mileage that the car can
obtain. A random sample of 20 cars’ weights and mileage is
collected. The table for the weight and mileage of the cars is
given below. Use Excel to find the best fit linear regression
equation, where weight is the explanatory variable. Round the slope
and intercept to three decimal places.

Car battery
The mileage of a car battery is exponentially distributed with a
mean value of 10000 km.
(a) What is the probability of a 5000 km trip without
replacement of the battery?
(b) What is the maximum length of travel that can be terminated
with 90% probability without replacing the battery?
(c) Determine the median, the mean and the variance of the
mileage of the battery

(a) How many of these functions are strictly increasing (i.e.
f(1) < f(2) < f(3) < f(4) < f(5) < f(6))? Hint: How
many different possibilities are there for the range of f? For each
range of f, how many strictly increasing functions are there?
