"8. Just as was the case with the z for a sample mean, the single-sample t test, and the related samples t test, you must compute the amount of sampling error that is "expected by chance or sampling error" before you can determine if the null hypothesis is likely or unlikely to be true. The acetaminophen and control groups each had 31 people with social pain SDs of 18 and 20, respectively. Use the two equations provided below to compute the value for standard error of the mean difference, estimated sampling error.
SDp2=(n11)SD12+(n21)SD22(n11)+(n21)=
SEMi=SDp2n1+SDp2n2=
