A weight-loss clinic advertised that last month its patients, on average, lost 7 lbs. Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true. If none of the statements is true, mark the appropriate box. Last month at least one of their patients lost 7 lbs or more. This month at least one of their patients will lose at least 7 lbs Last month, the number of their clients who lost more than 7 lbs was equal to the number of their clients who lost less than 7 lbs Last month all of their patients lost less than 11 lbs. Last month some of their patients lost exactly 7 lbs. None of the above statements is true.
An individual can take either a scenic route to work or a non-scenic route. She decides that use of the non-scenic route can be justified only if it reduces the mean travel time by more than 9 minutes. (a) If ?1 refers to the mean travel time for the non-scenic route and ?2 to the mean travel time for the scenic route, what hypotheses should be tested? ?1 − ?2 = −9 ?1 − ?2 < −9 ?1 − ?2 < −9 ?1 − ?2 > −9 ?1 − ?2 =−9 ?1 − ?2 ≠ −9 ?1 − ?2 = 9 ?1 − ?2 < 9 ?1 − ?2 = 9?1 − ?2 > 9 B) If ?1 refers to the mean travel time for the scenic route and ?2 to the mean travel time for the non-scenic route, what hypotheses should be tested? ?1 − ?2 = −9?1 − ?2 < −9 ?1 − ?2 = −9?1 − ?2 > −9 ?1 − ?2 = −9?1 − ?2 ≠ −9 ?1 − ?2 = 9?1 − ?2 < 9 ?1 − ?2 = 9?1 − ?2 > 9
