For each of the followingsituations, state whether a TypeI, a TypeII, or neither error has been made.

a) A test of H0: p=0.7 vs. HA: p0.7 rejects the null hypothesis. Later it is discovered that p=0.85.

b) A test of H0: p=0.1 vs. HA: p<0.1 failstoreject the null hypothesis. Later it is discovered that p=0.2.

c) A test of H0: p=0.5 vs. HA: p<0.5 failstoreject the null hypothesis. Later it is discovered that p=0.4.

d) A test of H0: =30 vs. HA: >30 rejects the null hypothesis. Later it is discovered that =29.9.
