T distribution is symmetric and t table gives values of t such that the probability of the larger t is equal to a given probability. Read the applicable rule before solving any problem. Show the formula, and graph where applicable.
1a) P(t > to) = 0.10 given a sample size of 13. Find to
1b) P(-to > t > + to) = 0.05 given a sample size of 9. Find to
1c) P(t < 2.1098) = ? given a sample size of 18. Find the associated probability.
