I was a little fuzzy on t.test before today. I remembered how to find Tn-1 ~ (xbar-mu)/(s/sqrt(n)) where s is the sample standard deviation and to get p value by using pt(teststat, df=n-1) but forgot that we could use t.test(samp, alternative=c(“two.sided”), conf.level=.95) to find out if the Ho is rejected or failed to be rejected. Overall, today was a great review day.
