Well, the normal force and the force of gravity are equal, however, they travel in opposite directions. Mass never changes and temperature has to do with the ambient environment and the object itself. That eliminates 3 and 4. The force of gravity pulls downwards as we see it, so that eliminates option 1. Your answer is option 2.
Answer: The object would move up or down(Option 2)
Using the z-distribution, it is found that a sample of 171 should be selected.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

The margin of error is:

In which:
is the sample mean.
is the standard deviation for the population.
For this problem, the parameters are:

Hence we solve for n to find the needed sample size.





n = 170.7.
Rounding up, a sample of 171 should be selected.
