A reseаrch cоnglоmerаte is studying sоciаl mobility indices (SMI) in the United States. They wanted to determine if different states' SMIs differ from the established average of 70.4. Four different researchers each drew their own samples from a different state, computed summary statistics from the raw data, and calculated the following 95% confidence intervals: Arkansas: (66.8, 69.2) Arizona: (70.3, 71.3) Montana: (61.0, 80.1) New Hampshire: (74.4, 76.6) Select all states that statistically differ from the established average.
