Question: Let n = 9 in the T statistic defined in Equation 5.5-2. (a) Find t0.025 so that P(t0.025 T t0.025) = 0.95. (b)

Let n = 9 in the T statistic defined in Equation 5.5-2.
(a) Find t0.025 so that P(−t0.025 ≤ T ≤ t0.025) = 0.95.
(b) Solve the inequality [−t0.025 ≤ T ≤ t0.025] so that μ is in the middle.
