An ammeter can measure current upto 500ma. there are 20 equal division between 0 and 100ma mark on its scale. during an experiment to determine the equivalent resistance of the two resisters joined in parallel a student observes ammeter’s pointer at 3rd graduation mark after zero when the key is off and the pointer at the 17th graduation mark after 200ma when the key is inserted into the plug. the correct value of the current flowing in the circuit is

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
