WebH 1: The two populations are not equal. This test is often performed as a two-sided test and, thus, the research hypothesis indicates that the populations are not equal as opposed to specifying directionality. Web(a)For a light source at redshift zthat is observed at time t 0, show that z changes at a rate dz dt 0 = H 0(1 + z) H 0(1 + z)3(1+w)=2: (1) Solution Starting from the relationship between zand a, 1 + z= a(t 0) a(te), and the de nition of the Hubble parameter H(t) = 1 a(t) da(t) dt, we can solve for dz=dt 0 in terms of H 0. First, note that as ...

WebSep 10, 2008 · A common and simple approach to evaluate models is to regress predicted vs. observed values (or vice versa) and compare slope and intercept parameters against the 1:1 line. However, based on a review of the literature it seems to be no consensus on which variable (predicted or observed) should be placed in each axis.
