The appropriate hypothesis test for this question is the two proportions test. As the name implies, it is often used to compare existing percentages between two groups. The raw data behind the percentages must be available as the sample size becomes crucially important in determining the test statistics.
The test statistic of the two-proportion test is the Z value. When the sample becomes very large, the Z value is governed under a normal function and is commonly known as the standardized Z value
Answer:
The coefficient of kinetic friction between the puck and the ice is 0.05.
Explanation:
Given that,
Weight of the hockey puck, W = mg = 3.5 N
Acceleration of the hockey puck,
The frictional force opposing the motion of the puck is given by
This force is balanced by the force due to motion of the hockey puck. So,
or
So, the coefficient of kinetic friction between the puck and the ice is 0.05. Hence, this is the required solution.

The net force! That would be the total force off all the forces acting on an object. :)
Answer:
The reagents correspond to substances that react with others, generating a chemical reaction.
Explanation:
Example:
H2 + 02 -> H202
Hydrogen reacts with oxygen in a synthesis reaction, forming a new compound (hydrogen peroxide) called a product.
