Final answer:
The statement about the learning rate can be true as values greater than 1 are possible but uncommon; the position vs time graph should be a curve for acceleration; experiments can be done on humans with ethical considerations; larger sample sizes in experiments are generally preferred; the GRASP CHECK answer is false as speed can be equal to or greater than velocity depending on the direction of motion.
Step-by-step explanation:
The statement "The value of the learning rate is not always between 0 and 1" is True. In machine learning, the learning rate can sometimes be set higher than 1, although it is not common as it can cause the algorithm to overshoot the minimum of the loss function. However, in most practical cases, the learning rate is set between 0 and 1 to ensure smooth convergence.
As for the statement "The position vs time graph of an object that is speeding up is a straight line", the answer is False. The correct statement is that the position vs time graph of an object that is speeding up is a curve that grows steeper over time if the acceleration is constant. A straight line would indicate constant speed, not acceleration.
Regarding the statements about scientific experiments, "Experiments cannot be done on humans" is False. Experiments can be done on humans but require rigorous ethical considerations and approvals. Lastly, the statement "Larger sample sizes are generally better than smaller ones in scientific experiments" is True, as they can provide more accurate and reliable results.
Finally, the GRASP CHECK statement is False. The average speed of a ball can be equal to or greater than the average velocity if the motion is entirely in one direction; otherwise, if the ball changes direction, the average speed might be greater because speed is a scalar quantity not considering direction, unlike velocity.
