$25\mathrm{.}28$ Software gives chi$-$square statistic ${}^2=325\mathrm{.}459$ for this table. From the table of critical values, we can say that the $P-$value is

$($a$)$ between $0\mathrm{.}0025$ and $0\mathrm{.}001.$

$($b$)$ between $0\mathrm{.}001$ and $0\mathrm{.}0005.$

$($c$)$ less than $0\mathrm{.}0005.$
