(a) In a hypothetical study, 10 patients with kidney disease were randomly assigned to receive two dialysis methods (A and B). 5 patients received Dialysis-A followed by Dialysis-B, and the remaining 5 received Dialysis-B followed by Dialysis-A. The kidney function scores of these patients are given as:

  Group-I (AB Sequence)        
Patient No. 1 2 3 4 5
Dialysis-A 69 73 50 69 76
Dialysis-B 68 79 68 72 85
  Group-II (BA Sequence)        
Patient No. 6 7 8 9 10
Dialysis-B 57 70 75 70 69
Dialysis-A 51 71 53 62 64

Test whether the mean score for dialysis-A is different from the mean score of dialysis-B, assuming no carry-over effect.

In a quantal assay, the number of cured cases for five doses of a standard and four doses of a new test drug are recorded in the following table:

  d_i} {n_i}$ {r_i}
Standard 3 28 4
  6 30 8
  9 24 12
  12 32 22
  15 27 21
Test 2 31 3
