TUGAS PENDAHULUAN
STATISTIKA NON PARAMETRIK
1. The following data represent the time, in minutes, that a patient has to wait
during 12 visits to a doctor's office before being seen by the doctor:
17 15 20 20 32 28
12 26 25 25 35 24
Use the sign test at the 0.05 level of significance to test. the doctor's claim
that the median waiting time for her patients is not more than 20 minutes
before being admitted to the examination room.
2. A cigarette manufacturer claims that the tar content of brand B cigarettes is
lower than that of brand A. To test this claim, the following determinations
of tar content, in milligrams, were recorded:
Use the rank-sum test with a = 0.05 to test whether the claim is valid.
3. A consumer panel tests 9 brands of microwave ovens for overall quality.
The ranks assigned by the panel and the suggested retail prices are as
follows:

Is there a significant relationship between the quality and the price of a
microwave oven? Use a 0.05 level of significance.
4. A study by a chemical company compared the drainage properties of two
different polymers. Ten different sludges were used and both polymers
were allowed to drain in each sludge. The free drainage was measured in
ml/min.
a. Use the sign test at the 0.05 level to test the null hypothesis that polymer A
has the same median drainage as polymer B.
b. Use the signed-rank test to test the hypotheses of part (a).
