For each pair of hypotheses that follows, decide whether H and H are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select "Valid" from the drop down menu. If not, select "Invalid".

1	H: M = 30		2	H: = 115
	H: M 30			H: 115

3	H: = 210		4	H: = 130
	H: 210			H: 138

You evaluate the by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.
