We calculate the inclusive branching ratio for B → Xsγ, the inclusive branching ratios and asymmetries for B → Xsl + l − , and the anomalous magnetic moment gµ − 2 of the muon, within a minimal gauge-mediated SUSY-breaking model which naturally generates a large ratio tan β of Higgs field vacuum expectation values. These predictions are highly correlated with each other, depending on only two fundamental parameters: the superpartner mass scale and the logarithm of a common messenger mass. The predictions for B → Xsγ decay and gµ−2 are in somewhat better agreement with current experiments than the standard model, but a much sharper comparison will soon be possible using new measurements now in progress or under analysis. Moreover we predict large deviations in B → Xse + e − and B → Xsµ + µ − asymmetries, and somewhat smaller ones in B → Xse + e − and B → Xsτ + τ − branching ratios, which will be detectable in
