In 811, write the given higher-order equation or system in an equivalent normal form (compare Section 5.3).
Comparing two means: sections 9.1 and 9.2 Matched pair assumptions: o Matched pairs is a special test when we are comparing corresponding values in data o The test is only used when the data samples are dependent upon one another o Matched pairs ttest assumptions: Each sample is an SRS of size n from the same population The test is conducted on paired data Unknown population standard deviation Either a normal population or large samples Rcode: o > auth=c(797,571,904,1147,418) > indep=c(523,488,875,911,297) > t.test(auth,indep,conf.level = 0.95, paired = TRUE) Paired ttest data: auth and indep t = 3.2148, df = 4, pvalue = 0.03244
