Answer #1

Answer (A) Precentral gyrus.

The precentral gyrus, which may also be called the primary motor area or most commonly, the motor strip is immediately anterior to the central sulcus. It controls the voluntary movements of skeletal muscles.

Finger - tapping speed and grip strength are one of the most widely used measures of manual dexterity. the test assesses fine motor speed and dexterity and provides an indicator of the over all function of the motor strip and precentral gyrus.

For the following experiments/questions, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...
