STATISTIKA INDUSTRI 2

STATISTIKA NON PARAMETRIK

1. The following data represent the number of hours of flight training received by 18

student pilots from a certain instructor prior to their first solo flight:

9 12 18 14 12 14 12 10 16 11 9 11 13 11 13 15 13 14

Using binomial probabilities, perform a sign test at the 0.02 level of significance to

test the instructor’s claim that the median time required before his students’ solo is 12

hours of flight training.

2. The following are the numbers of prescriptions filled by two pharmacies over a 20-

day period:

Use the signed-rank test at the 0.01 level of significance to determine whether the two

pharmacies, on average, fill the same number of prescriptions against the alternative

that pharmacy A fills more prescriptions than pharmacy B.

3. A fishing line is being manufactured by two processes. To determine if there is a

difference in the mean breaking strength of the lines, 10 pieces manufactured by each

process are selected and then tested for breaking strength. The results are as follows:

4. Use the rank-sum test with α = 0.1 to determine if there is a difference between the

mean breaking strengths of the lines manufactured by the two processes. 4. The

following data represent the operating times in hours for three types of scientific

pocket calculators before a recharge is required:

Use the Kruskal-Wallis test, at the 0.01 level of significance, to test the hypothesis

that the operating times for all three calculators are equal.
