Given the following latin square design using $4$ treatments a$,$ b$,$ c$,$ d$.$

$\backslash$table$[[10($b$),4($d$),6($a$),10($c$)],[20($d$),10($a$),12($c$),8($b$)],[5($a$),22($c$),1($b$),5($d$)],[4($c$),12($b$),5($d$),2($a$)]]$

$($a$)$ Compute the efficiency of the design over randomized block design by assuming rows as blocks.

$($b$)$ Compute the efficiency of the design over completely randomized design.
