b.)

c.)

d.)

e.)
sigma

========================================================

Explanation:

The symbol [tex]\mu[/tex] or mu represents the population mean, which is a parameter.

The symbol [tex]\sigma[/tex] 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 choices B and C as our final answers.

[tex]\overline{x}[/tex] or xbar is a sample statistic, and it represents an estimate of the population mean. Similarly, [tex]\hat{p}[/tex] 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.

A parameter, represented by the symbol mu, is the population mean.

Thus, The population standard deviation, another parameter, is denoted by the letter sigma. The symbol p, which stands for population proportion and has no hat on top, is equivalent.

Something is inherently a parameter if it represents a population data item. It could be helpful to remember that the words "parameter" and "population" both begin with the letter P.

We can eliminate options A, D, and E based on the sentences above. These three things are constraints and parameter. This leaves B and C as our only remaining options. In a similar manner, or p-hat is the sample proportion and it and population.

Thus, A parameter, represented by the symbol mu, is the population mean.

Elizabeth had grown up amidst the liberal culture of Henry's court, a bold horsewoman, a good shot, a graceful dancer, a skilled musician, and an accomplished scholar. She studied every morning and could "rub up her rusty Greek" as needed. The new literature which was springing up around her found constant welcome in her court. She spoke Italian and French as fluently as her mother tongue; she was familiar with Ariosto and Tasso and listened with delight to the writings of "Master Spenser."

Her moral temper recalled in its strange contrasts the mixed blood within her veins. She was at once the daughter of Henry VIII and Ann Boleyn. From her father she inherited her frank and hardy address, her courage and self-confidence; her pride and furious outbursts of anger also came from the Tudor blood. Her sensuous and self-indulgent nature she inherited from Ann. Splendor and pleasure were with Elizabeth the very air she breathed. She loved gaiety, laughter, and wit. Her vanity remained even to old age, the vanity of a coquette.

It was no wonder that statesmen whom she outwitted held Elizabeth I almost to the last to be little more than a frivolous woman. But the Elizabeth whom they saw was far from being all of Elizabeth. The willfulness of Henry and the triviality of Ann played over the surface of a nature as hard as steel, a purely intellectual temperament. Her vanity and caprice had no weight whatever with her in state affairs. The coquette of the presence-chamber became the coolest and hardest of politicians at the council-board. It was this part which gave her her marked superiority over the statesmen of her time. No nobler group of ministers ever gathered round the council-board than those of Elizabeth. But she was the instrument of none. She listened, she weighed, she used or put by the counsels of each in turn, but her policy, as a whole, was she own. It was a policy of good sense, not genius. She endeavored to keep her throne, keep England out of war, and restore civil and religious order.
