A
golf association requires that golf balls have a diameter that is
1.68 inches. To determine if golf balls conform to the standard, a
random sample of golf balls was selected. Their diameters are as
follows:
1682, 1684, 1684, 1685, 1677, 1679, 1684, 1682, 1682, 1685,
1673, 1675.
Do the golf balls conform to the standards? Use a= 0.05 level
of significance.
First, determine the appropriate hypotheses.
what is the test statistic?
what is the p value?
Reject, do not reject, why?
Solutions

A golf association requires that golf balls have a diameter that
is
1.681.68
inches. To determine if golf balls conform to the standard, a
random sample of golf balls was selected. Their diameters are shown
in the accompanying data table. A normal probability plot suggests
that the population from which the sample was drawn is normal, and
the boxplot of the data shows no outliers.Do the golf balls conform
to the standards? Use the
alphaαequals=0.010.01
level of significance.

The design of an automotive gear requires the diameter to be 4
inches. To evaluate the production quality, you sample 30 gears and
find the average to be 4.11 with a standard deviation of 0.67.
Construct a hypothesis test at a 0.05 level of significance to
determine if the gear diameter is larger than 4 inches.
Select one:
a. The critical value is 2.05, the test statistic is 0.90,
conclude the gear diameter is not equal to 4 inches
b....

The International Tennis Federation (ITF) requires that tennis
balls have an average diameter of 6.7 centimetres. Tennis balls
being produced by one manufacturer are tested to see if they fail
to meet the ITF standard. A random sample of 9 tennis balls had a
mean diameter of 6.55 cm, with standard deviation 0.12 cm. Assume
tennis ball diameter is normally distributed.
