The answer is the third one (or C): quadriceps femoris group.

Explanation for each option:

  • Gastrocnemius: This muscle is located in the calf and is primarily innervated by the tibial nerve, not the femoral nerve.
  • Hamstring group: The hamstring muscles are located at the back of the thigh and are primarily innervated by the sciatic nerve, not the femoral nerve.
  • Quadriceps femoris group: This group of muscles is located at the front of the thigh and is innervated by the femoral nerve. The quadriceps femoris group includes the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius muscles.
  • Gluteus maximus: This muscle is located in the buttocks and is primarily innervated by the inferior gluteal nerve, not the femoral nerve.

Summary: The femoral nerve serves the quadriceps femoris group, which is responsible for extending the knee.

The P -value for a hypothesis test is shown. Use the P -value to decide whether to reject H₀ when the level of significance is (a) α=0.01, (b) α=0.05, and (c) α=0.10. P=0.0237 (a) Do you reject or fail to reject H₀ at the 0.01 level of significance? A. Fail to reject H₀ because the P -value, 0.0237, is greater than α=0.01. B. Fail to reject H₀ because the P-value, 0.0237, is less than α=0.01. C. Reject H₀ because the P-value, 0.0237, is greater than α=0.01. D. Reject H₀ because the P-value, 0.0237, is less than α=0.01. (b) Do you reject or fail to reject H₀ at the 0.05 level of significance? A. Reject H₀ because the P-value, 0.0237, is greater than α=0.05. B. Fail to reject H₀ because the P-value 0.0237, is less than α=0.05. C. Reject H₀ because the P-value 0.0237, is less than α=0.05. D. Fail to reject H₀ because the P-value, 0.0237, is greater than α=0.05.
