A model known as stopping sight distance is
used by civil engineers to design roadways. This
simple model estimates the distance a driver
needs in order to stop his car while traveling at
a certain speed after detecting a hazard. The
model proposed by the American Association
of State Highway and Transportation Officials
(AASHTO) is given by
V²
S =
2g(f±G)
+TV
where
S = stopping sight distance (ft)
V = initial speed (ft/s)
g = accelaration due to gravity, 32.2 ft/s?
f = coefficient of friction between tires
and roadways
G = grade of road
T = driver reaction time (s)
What are the appropriate units for f
and G if the preceding equation is to be
homogeneous in units? Show all steps of
your work.
Suppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz):
15.87 16.02 15.78 15.83 15.69 15.81 16.04 15.81 15.92 16.10
On the basis of these data, can you conclude that the mean fill weight is actually less than 16 oz?
State the appropriate null and alternate hypotheses.
Compute the value of the test statistic.
Find the P-value and state your conclusion.
