Multiple Choice

The coefficient of determination,or R-squared,is defined as:

• A) 1 - \(\Sigma\) (Y_i + Y_estimated)² / \(\Sigma\) (Y_i + Y_mean)².
• B) 1 - \(\Sigma\) (Y_i - Y_estimated)² / \(\Sigma\) (Y_i - Y_mean)².
• C) \(\Sigma\) (Y_i + Y_estimated)² / \(\Sigma\) (Y_i + Y_mean)².
• D) 1 - \(\Sigma\) (Y_i - Y_estimated) / \(\Sigma\)(Y_i - Y_mean).
• E) 1 - [\(\Sigma\) (Y_i - Y_estimated) / \(\Sigma\)(Y_i - Y_mean)]².

Neuromuscular Junction

Region where an axon bulb approaches a muscle fiber; contains a presynaptic membrane, a synaptic cleft, and a postsynaptic membrane.

Synapse
