For each of the following situations, state whether a Type I, a Type II, or neither error

Question:

For each of the following situations, state whether a Type I, a Type II, or neither error has been made.
a) A test of H0: ( = 25 vs. HA: ( >25 rejects the null hypothesis. Later it is discovered that ix = 24.9.
b) A test of HQ: p = 0.8 vs. HA: p <0.8 fails to reject the null hypothesis. Later it is discovered that p = 0.9.
c) A test of HQ: p = 0.5 vs. HA: p ≠ 0.5 rejects the null hypothesis. Later is it discovered that p = 0.65.
d) A test of H0: p = 0.7 vs. HA: p <0.7 fails to reject the null hypothesis. Later is it discovered that p = 0.6.
