Question

17-20: You are given two paired samples with the following information:

            Item     Sample 1        Sample 2

            1          19.6                 21.3

            2          22.1                 17.4

            3          19.5                 19.0

            4          20.0                 21.2

            5          21.5                 20.1

            6          20.2                 23.5

            7          17.9                 18.9

            8          23.0                 22.4he

            9          12.5                 14.3

           10        19.0                 17.8

Based on these paired samples, test at the α=0.05 level whether the true median paired difference is 0.

Answer 1

Answer:

Given Data

Degree of freedom:

= 10 - 1

= 9

= 10 - 1

= 9

Critical value(s):

Lower tailed critical value,

Fα/₂ = F.INV(0.05/2, 9, 9)

= 0.156
