Part IV. Interpreting Decision Instruction. Determine whether the claim represents the null hypothesis or the altermative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis? (b) fails to reject the null hypothesis? 1. Agovernment agency claims that more than 75% of full-time workers earn a minimum wage per week. 2. A researcher claims that the standard deviation of the life of a certain type of lawn mower is at most 2.8 years.
