A high speed 2L electric water heater is heated by a 2.5 kW heating element. How long does it take to have boiled water. After boiling water, we pour the boiled water to a open glass bottle to let the water cool down. Heat lose at the rate of 500 W to surrounding environment. How long do we have to wait to drink the water at 300C

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?
