scm week 8 notes t test paired samples now we will be running a hypothesis test to compare 2 means instead of testing one mean if we can block for a variable, we will use the paired ttest usually we want to test if the difference of 2 means is equal to 0. If the difference is equal to 0, then the 2 populations have the same mean the ttest for n1=15 and n2=15 using pared testing has a) 14 degrees of freedom b) 13 degrees of freedom c) 29 degrees of freedom d) 28 degrees of freedom e) 30 degrees of freedom T/F Assume a matched pairs test for a mean difference with a twotailed alternative hypothesis and the number of paired differences n=4. If the computed test statistic t=2.353, then the pvalue would be equal to .05.
