Answer 1

Yes,

Cheater affect the accreditation.

because, here we given that we need to new t-critical and we know t-critical value depend upon the significance level α, number of degrees of freedom and indicate the type of tail (left-tailed, right-tailed, or two-tailed) and degree of freedom depend on the n (sample size ) so here, if we removed 980, and 980 obsevation then sample size reduce and it affected on t-critical and t-critical affected on our decision.
