Liars X1= 1.52 s1=0.32 n1= 47 Truthful X2= 1.30 s2=0.39 n2= 4 This is a table summarizing the statistics between the number of words truthful people use vs people who are lying. To analyze this data; choose a t procedure, justify your choice, and perform it. Create a 95% confidence interval for (mean1 – mean2) and interpret this interval. Choose an appropriate hypothesis test and perform it (give hypothesis in words, symbols, test statistic, p-value, and conclusion) Interpret results.
