Per Step 2 of the 5-Steps to Hypothesis Testing, choose the appropriate

test statistic. Please note that 0 and 1 are defined as no and yes, respectively, which is a typical coding scheme in Public Health. Select one: MACROBUTTON HTMLDirect a. z = (X̄1 – X̄2) / [ Sp * √(1 / n1 + 1 / n2) ], where Sp = √( [(n1 – 1) * s12 + (n2 – 1) * s22] / [n1 + n2 – 2] ) MACROBUTTON HTMLDirect b. z = (p̂ – p0) / √(p0 * (1 – p0) / n), where p̂ = x / n MACROBUTTON HTMLDirect c. t = (X̄ – µ0) / (s / √n) MACROBUTTON HTMLDirect d. z = (p̂1 – p̂2) / √[ p̂ * (1 – p̂) * (1 / n1 + 1 / n2) ], where p̂1 = x1 / n1, p̂2 = x2 / n2, p̂ = (x1 + x2) / (n1 + n2) Please share your work
