In an investigation of the visual scanning behavior of deaf children, measurements of eye movement rates were taken on nine deaf and nine hearing children as shown in the table below. Does it appear that the distributions of eye-movement rates for deaf children and hearing children differ? Test at = 0.05 using the Wilcoxon rank sum test.
The null and alternate hypotheses are: : The distributions of eye-movement rates for hearing impaired children and hearing children are identical. : The distributions of eye-movement rates for hearing impaired children and hearing children are different.
What is the test statistic?
T: ______________
What is the critical value for the test statistic?
______________
Thus: ______________
Conclude:
We conclude that the hearing impaired children ______________ from the hearing children in eye-movement rate.
