Native American (#1) [8.50, 9.48, 8.65 ]

Caucasian (#2) [8.27, 8.20, 8.25, 8.14]

alpha = 0.15

b. Test the difference between the two group means using a permutation test.

Expert Solution

Using R language

install.packages("Stat5303libs")
library(Stat5303libs)
install.packages("cfcdae")

Native_American = c(8.50, 9.48, 8.65)
Caucasian= c(8.27, 8.20, 8.25, 8.14)
twoSamplePermutationTestLocation(Native_American,Caucasian)

p-value = 0.0282 < alpha

we reject the null hypothesis

there is significant difference
