Part 2: what is the claim? Part 3: what is the p-value? Select one: a. Part 1 H1 μ < 2.66 Part 2 H1 is the claim Part 3 p-val = 0.0000 b. Part 1 H1 μ < 2.29 Part 2 Ho is the claim Part 3 p-val = -10.070 c. Part 1 H1 μ ≠ 2.66 Part 2 Ho is the claim Part 3 p-val = 0.0000 d. Part 1 H1 μ ≠ 2.29 Part 2 Ho is the claim Part 3 p-val = 7.639
