In a test of H0H_0H0: p=0.25p = 0.25p=0.25 against H1H_1H1: p<0.25p < 0.25p<0.25, a sample gives P(X≤6)=0.0287P(X \le 6) = 0.0287P(X≤6)=0.0287.
State the conclusion of the test at the 5% significance level, giving a reason.
State the conclusion of the test at the 1% significance level, giving a reason.
