(a) 2 pts. What is the observed value of the test statistic used in the randomization test?

(b) 5 pts. Compute the randomization-based two-sided p-value for testing the null hypothesis

of no effect of washing. If you have insufficient information, indicate what addition information you need.

I'm not sure how to calculated a randomization test without the actual data. Could anyone explain the process to me?
