Q: It is worth noting that the confidence interval for a parameter is not the same as the acceptance region of a test for this parameter, as is sometimes thought. The confidence interval is part of the parameter space, whereas the acceptance region is part of the sample space. For the same reason, the confidence level is not the same as the complementary probability of the level of significance.
Can we conclude that is significance level the same as confidence interval?
A: no

Q: The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which in turn contains the Milky Way and Andromeda galaxies. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years). The Virgo SC is one of about 10 million superclusters in the observable universe and is in the Pisces--Cetus Supercluster Complex, a galaxy filament.
Can we conclude that does the milky way belong to a galaxy cluster?
A: yes

Q: He is killed in the season 3 episode ''The Murder of One'', when Stefan, Elena and Matt kill him, thinking that it will kill all of the Originals due to their ''linked'' status. However, Klaus manages to force Bonnie into unlinking the siblings moments before Finn is killed. It is revealed through Finn's death that when an Original dies, all vampires of his or her bloodline die as well.
Can we conclude that do any of the originals die in the originals?
A: yes

Q: The atomic mass (m) is the mass of an atom. Its unit is the unified atomic mass units (symbol: u, or Da) where 1 unified atomic mass unit is defined as of the mass of a single carbon-12 atom, at rest. For atoms, the protons and neutrons of the nucleus account for almost all of the mass, and the atomic mass measured in u has nearly the same value as the mass number.
Can we conclude that is the mass of an electron taken into account for the atomic mass?
A:
no
