Answer:

A rate: a measure, quantity, or frequency, typically one measured against some other quantity or measure.

A unit rate: When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Hope this helps.

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

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