Suppose you have the following data, with a mean and standard deviation of 5 and 2.1 3 3 4 5 7 8 If you were to subtract 2 from every observation, what change - if any- would you see in the transformed mean and standard deviation? the mean and standard deviation would decrease the mean wold stay the same but the standard deviation would decrease the mean and standard deviation would stay the same the mean would decrease but the...
The drawings show three charges that have the same magnitude
but may have different signs. In all cases the distance d between
the charges is the same. The magnitude of the charges is |q|=9.1
μC, and the distance between them is d=5.3 mm. Determine the
magnitude of the net force on charge 2 for each of the three
drawings.

If the sample mean and sample standard deviation are the same when doing a study with an unknown mean and standard deviation of the population. What effect does increasing the sample size have on The P value and the margin of error (assuming the same confidence level)? Also, what effect does increasing the sample size have on the width of the confidence interval (assuming the same confidence level)?
The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q|=9.4 muC, and the distance between them is d= 3.3 mm. Determine the magnitude of the net force on charge 2 for each of the three drawings.
