a commonly cited standard for one - way length (duration) of school bus rides for elementary school children is 30 minutes.\na local government office in a rural area conducts a study to determine if elementary schoolers in their district have a longer average one - way commute time. if they determine that the average commute time of students in their district is significantly higher than the commonly cited standard they will invest in increasing the number of school busses to help shorten commute time. what would a type 2 error mean in this context?\n○the local government decides that the average commute time is 30 minutes.\n○the local government decides that the data provide convincing evidence of an average commute time higher than 30 minutes, when the true average commute time is in fact 30 minutes.\n○the local government decides that the data do not provide convincing evidence of an average commute time higher than 30 minutes, when the true average commute time is in fact higher than 30 minutes.\n○the local government decides that the data do not provide convincing evidence of an average commute time different than 30 minutes, when the true average commute time is in fact 30 minutes.\nquestion help: video message instructor

Answer

# Brief Explanations: A Type 2 error occurs when we fail to reject a false null hypothesis. In this case, the null hypothesis is that the average commute - time is 30 minutes and the alternative is that it is higher than 30 minutes. A Type 2 error means we do not have convincing evidence to say the average commute time is higher than 30 minutes when in fact it is higher. # Answer: The local government decides that the data do not provide convincing evidence of an average commute time higher than 30 minutes, when the true average commute time is in fact higher than 30 minutes.
