D
I say D because high school has more specific schedules where in college there is more freedom with your schedule.
Answer: 42,500
Explanation:
based on the graph the best answer to go with is 42,500 since it’s past 40,000 and not quite at 45,000. let me know if it’s correct or not, sorry if it won’t be in advance
<h3>
Answers: Choice B and Choice C</h3>
========================================================
Explanation:
The symbol 
or mu represents the population mean, which is a parameter.
The symbol 
or sigma represents the population standard deviation, which is also a parameter. The same goes for the symbol p, without any hat on top, as it is the population proportion.
If something represents a population data item, then it's automatically a parameter. It might help to think both words "population" and "parameter" start with the letter P.
Based on those previous paragraphs, we can rule out choices A, D and E. Those three items are parameters. This leaves <u>choices B and C</u> as our final answers.
or xbar is a sample statistic, and it represents an estimate of the population mean. Similarly, 
or p-hat is the sample proportion and it represents an estimate of the population proportion. These are considered unbiased estimators.
Another example of an unbiased estimator is the variable s which represents the sample standard deviation and it estimates the value of sigma. All of these estimators have one thing in common: they are based on a sample, which in turn tries to predict what the corresponding population value is. In other words, the statistic's job is to estimate the parameter.
Below is a reference table for all of the items mentioned.
15,000 + 400 + 9
Or
(1x10,000)+(5x1,000)+(4x100)+(0x10)+(9x1)
"Forebears" means ancestors. By invoking the memory and stature and wisdom of those who "prescribed" the "solemn oath" used to swear new presidents into office, President Kennedy was connecting his new administration with all the history and accomplishment of preceding administrations. He was hoping to emphasize a connection with values upon which the United States was founded. Hope you find this useful!
