Two random samples were taken to determine how often people in a community listen to the local radio station
the first sample survey 15 people as they exited the bank on Main Street the first simple found that the mean number of the hours they listed the radio each month was 20
second sample surveyed every six person day exited the only local Griffin until a hundred people were surveyed the second sample sounds. The mean number of hours but it was good to the radio was each month was 12
which statements are true check all that apply
second sample is Random
the second sample is likely to be more representative of the population
the first sample is unlikely to be more representative of the population
the second sample will give a better representation because it's larger
the first sample will give a better representation because it's smaller

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
