Customer Question
1 Find the mean of the following set of numbers.
6, 9, 8, 12, 5
(6+9+8+12+5) /5
= 40/5
= 8
2 Find the mean of the following set of numbers.
12, 16, 19, 22, 28, 30
(12+16+19+22+28+30)/6
= 127/6
= 21.1666666666666666666
3 Find the median of the following set of numbers.
4, 5, 6, 9, 11
Since list is already sorted in ascending order
Median = middle element = 6
4 Find the median of the following set of numbers.
49, 23, 54, 48, 59, 58
Arranging list in ascending order
23,48,49,54,58,59
Since number is even so median = middle element= 49,54
5 The following scores were recorded on a 100point examination:
91, 85, 76, 86, 96, 51, 68, 92, 85, 72, 66, 88, 93, 82, 84
a) find the mean final examination score.
b) find the median final examination score.
mean = (91+85+76+86+96+51+68+92+85+72+66+88+93+82+84 ) =1215/15=81
Arranging list in ascending order 51,66,68,72,76,82,84,85,85,86,88,91,92,93,96
Since number is odd so median = middle element = 85
6 Find the mode of the following set of numbers.
11, 10, 6, 11, 12
Mode = 11(Since it occurs the most at 2 times )
7
Use the world population and land area table. What is the total land area
in Oceana as a percent of Earth?
8 Use the world population and land area table. What was the percent increase in population in Oceana from 1950 to 2000?
9 Food costs (thousands of dollars)
Use the graph (above) showing the yearly food costs of a family. What was the
mean (to the nearest cent) of the food for this family in the 7 years from
1999 to 2005?
10 What was the increase in the cost of food from 2001 to 2002?
11 The following pie chart shows the budget for a local company. The total budget
is $820,000. Find the amount budgeted in the category of operating expenses.
12 Find the first and third quartiles, and , of the following set of numbers.
14, 3, 13, 17, 6, 15, 6, 2, 11, 6
Sorting the data in ascending order 2,3,6,6,6,11,13,14,15,17
Q1 = Median of2,3,6,6,6=6
Q3 = Median of11,13,14,15,17=13
13 Find the fivenumber summary of the following set of numbers.
13, 3, 12, 18, 4, 14, 4, 1, 10, 4
In ascending order: 1,3,4,4,10,12,13,18
First sort...
1, 3, 4, 4, 4, 10, 12, 13, 14, 18
the minimum = 1
the minimum = = 4
the median = (10 + 4)/2 = 7
the upper quartile = 13
the maximum = 18
The median in this case is the average of the two middle values (10 and 4) because there is an even number of values.
The lower quartile is just the median of the first set of 5, and the upper quartile is the median of the second set of 5.
14 Find the fivenumber summary of the following set of numbers.
337, 248, 157, 388, 248, 451, 271, 225, 310
First sort... 157,225,248,271,310,337,388,451.
the minimum = 157
the minimum = =271
the median = (271+310)/2= 290.5
the upper quartile=
