We present a combination of searches for the standard model Higgs boson using the full CDF run II data set, which corresponds to an integrated luminosity of 9.45-10.0 fb super(-1) collected from radicals = 1.96 TeV pp collisions at the Fermilab Tevatron. The searches consider Higgs boson production from gluon-gluon fusion, vector-boson fusion, and associated production with either a W or Z boson or a tt pair. Depending on the production mode, Higgs boson decays to W super(+)W super(-), ZZ, bb, tau super(+)tau super(-), and gamma gamma are examined. We search for a Higgs boson with masses (m sub(H)) in the range 90-200 GeV /c super(2). In the absence of a signal, we expect based on combined search sensitivity to exclude at the 95% credibility level the mass regions 90 < m sub(H) < 94 GeV /c super(2), 96 < m sub(H) < 106 GeV /c super(2), and 153 < m sub(H) < 175 GeV /c super(2). The observed exclusion regions are 90 < m sub(H) < 102 GeV /c super(2) and 149 < m sub(H) < 172 GeV /c super(2). A moderate excess of signal-like events relative to the background expectation at the level of 2.0 standard deviations is present in the data for the m sub(H) = 125 GeV /c super(2) search hypothesis. We also present interpretations of the data within the context of a fermiophobic model and an alternative standard model incorporating a fourth generation of fermions. Finally, for the hypothesis of a new particle with mass 125 GeV /c super(2), we constrain the coupling strengths of the new particle to W super(+ or -) bosons, Z bosons, and fermions.
