The 2010 General Social Survey asked the question, "After an average work day, about how many hours do you have to relax or pursue activities that you enjoy?" to a random sample of 1,155 Americans. The average relaxing time was found to be 1.65 hours. Determine which of the following is an observation, a variable, a sample statistic, or a population parameter.

a. Observation= An American in the sample.

b. Variable= Number of hours relaxing after a work day.

c. Sample statistic= 1.65

d. Population parameter= Average number of hours all Americans spend relaxing after the days work.

Step-by-step explanation:

-Observation is the value of something that interests the researcher.

- Variable is the characteristic of the unit being observed by the researcher which is number of hours relaxing after the day's work.

- Sample statistic is the value of the estimate of the descriptive statistic in a sample which is the mean of relaxing hours (1.65).

- Population parameter is the numeric value for a given population and in this, it is the Average numeric hours all Americans spend relaxing at work.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
