A recent study investigated the population size of burrowing owls in the Imperial Valley. In 2015, a random sample of 8 sites were selected and the number of burrowing owls were counted. In 2020, the researchers returned to the same sites and re-surveyed for owls. The data in the table represents the number of owls per site (population size) in 2015 and 2020. The column labeled "Difference" = 2020-2015 Site 2015 2020 Difference A 50 44 -6 51 47 -4 C 52 43 -9 37 31 -6 36 31 -5 39 30 -9 48 44 -4 37 33 -4 Mean: 43.8 37.9 -5.9 S: 7.1 7.2 2.1 Use the information given to determine if there is evidence of a significant population decrease since 2015 and answer the following questions. 1.
