Answer: c. sampling error
Step-by-step explanation:
- A population parameter is a number that is evaluated to describe the whole population . For example : Population mean , Population standard deviation etc.
- A sample statistic gives the estimate value of the population parameter. For example : Sample mean , sample proportion.
Since, the sample is a subset of population , so there are chances for unavoidable variation in sample mean from the population mean that varies from sample to sample .
This variation is known as sampling error.
∴ The difference between the value of the sample statistic and the value of the corresponding population parameter is called the sampling error .
Hence,the correct answer is c. sampling error .
Answer:
250; 
Step-by-step explanation:
a. 15 minutes passed, so there would be 250 people who came in
b. You would create a formula, where t = time after 8:15 (in minutes), while p = people who are at the parade
, which equals
The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:
- Amount of time x change per second = total change
- 135 x (-6) = X
- -810 = X
Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
