Predict the number of blue squares in a quilt with 11 green squares if there are 4 green squares in a quilt with blue squares.

attashe74 [19]

If you make the numbers into a ratio, it will be easier to find the answer.

There are 68 blue squares for the 4 green squares in the quilt.

68:4, or 68/4

If we do the division of the ratio, 68/4, we end up with 17.

Now, we multiply that by the 11 green squares of the new quilt.

17 x 11 = 187

There are five sales associates at Mid-Motors Ford. The five associates and the number of cars they sold last week are: Sales As

Levart [38]

Answer:

a) There are 10 different samples of size 2.

b) See the explanation section

c) See the explanation section

Step-by-step explanation:

a) We need to select a sample of size 2 from the given population of size 5. We use combination to get the number of difference sample.

$\{ {{5} \atop {2}} \} = \frac{5!}{2!(5-2)!} \\= \frac{5!}{2!3!} \\= \frac{120}{2*6} \\= \frac{120}{12} \\=10$

b) Possible sample of size 2:

Peter Hankish 8 Connie Stallter 6 Juan Lopez 4 Ted Barnes 10 Peggy Chu 6

Peter Hankish and Connie Stallter ( Mean = (8 + 6)/2 = 14/2 = 7)
Peter Hankish and Juan Lopez (Mean = (8 + 4)/2 = 12/2 = 6)
Peter Hankish and Ted Barnes (Mean = (8 + 10)/2 = 18/2 = 9)
Peter Hankish and Peggy Chu (Mean = (8 + 6)/2 = 14/2 = 7)
Connie Stallter and Juan Lopez (Mean = (6 + 4)/2 = 10/2 = 5)
Connie Stallter and Ted Barnes (Mean = (6 + 10)/2 = 16/2 = 8)
Connie Stallter and PeggyChu (Mean = (6 + 6)/2 = 12/2 = 6)
Juan Lopez and Ted Barnes (Mean = (4 + 10)/2 = 14/2 = 7)
Juan Lopez and Peggy Chu (Mean = (4 + 6)/2 = 10/2 = 5)
Ted Barnes and Peggy Chu (Mean = (10 + 6)/2 = 16/2 = 8)

c) The mean of the population is:

$mean = \frac{(8+6+4+10+6)}{5} \\= \frac{34}{5} \\= 6.8$

Comparing the mean of the population and the sample; we can say that most of the 2-size sample have their mean higher than that of the population sample. And the variation with the mean is not much. Some sample have their mean greater than population mean, while some sample have their mean greater than the population mean.
