ACTIVITY / EXERCISES
1.       The number of incorrect answers on a true-false competency test for a random sample of 15 students were recorded as follows: 2, 1, 3, 0, 1, 3, 6, 0, 3, 3, 5, 2, 1, 4, and 2. Find
(a)    the mean;
(b)   the median;
(c)    the mode.
2.       The number of building permits issued last month to 12 construction firms in a small Midwestern city were 4, 7, 0, 7, 11, 4, 1, 15, 3, 5, 8, and 7. Treating the data as a population, find
(a)    the mean;
(b)   the median;
(c)    the mode.
3.        The reaction times for a random sample of 9 subjects to a stimulant were recorded as 2.5, 3.6, 3.1, 4.3, 2.9, 2.3, 2.6, 4.1, and 3.4 seconds. Calculate
(a)    the mean;
(b)   the median.
4.       The employees of a local manufacturing plant pledged the following donations, in dollars, to the United Fund: 10, 40, 25, 5, 20, 10, 25, 50, 30, 10, 5, 15, 25, 50, 10, 30, 5, 25, 45, and 15. Treating the data as a population, calculate
(a)    the mean;
(b)   the mode.
5.       According to ecology writer Jacqueline Killeen, phosphates contained in house-hold detergents pas right through our sewer system causing lakes to turn into swamps that eventually dry up into deserts. The following data show the amount of phosphates per load of laundry, in grams, for a random sample of various types of detergents used according to the prescribed directions:
Laundry Detergents
Phosphates per load (gm)
A & P Blue Sail

For the given phosphate data, find
(a)    the mean;
(b)   the median;

(c)    the mode.
