#### Answer

a)reject the null hypothesis
b)there is sufficient evidence to support that the percentage of blue M&Ms is more than 5%.

#### Work Step by Step

a) If the P-value is less than $\alpha$, which is the significance level, then this means the rejection of the null hypothesis. Hence:P=0.001 is less than $\alpha=0.05$, hence we reject the null hypothesis.
b) Hence this means that there is sufficient evidence to support that the percentage of blue M&Ms is more than 5%.
