b. Let c, be the number of MAD values in the first sample that are greater than the largest MAD value in the second sample. Also, let c, be the number of MAD values in the second sample that are greater than
the largest MAD value in the first sample.
c. If the sample sizes are equal, use a critical value of 5. If not, use the formula below to find the critical value.
log (a/2)
