For each of the following scenarios, state the claim and whether or not it is supported. A.  A researcher claims that men, on average, can’t wait even 5.0 seconds without pressing a button on the tv remote control (i.e., average time between remote control use).  Assuming that a hypothesis test has been conducted and that the conclusion is to reject the null hypothesis, answer the following questions.    The claim is an [claim1] (enter H0 or H1) and is mu [symbols1] 5.0 seconds (enter correct sign(s))   Is the claim supported? [support1] (enter yes or no) B.  A cereal company claims that the proportion of cereal boxes that meet its weight specification is at least 95%. Assuming that a hypothesis test has been conducted and the conclusion is, fail to reject the null hypothesis, answer the following questions.    The claim is an [claim2] (enter H0 or H1) and is p [symbols2] 95% (enter correct sign(s))   Is the claim supported?
