What is the difference between population parameters and estimates in a sample?
Anna35 [415]

Answer:

Using that sample, you calculate the corresponding sample characteristic, which is used to summarize information about the unknown population characteristic. The population characteristic of interest is called a parameter and the corresponding sample characteristic is the sample statistic or parameter estimate.

Step-by-step explanation:

If you collect a sample and calculate the mean and standard deviation, these are sample statistics.

When drawn in standard position, an angle a has a terminal ray that lies in the second quadrant and whose sine is equal to 9/41.
Semenov [28]

Answer:

\frac{40}{41}

Step-by-step explanation:

We have the angle in standard post has a sine ratio of

\frac{9}{41}

This means the opposite side length of the corresponding right triangle is 9 units and the hypotenuse is 41 units.

Using Pythagoras Theorem, the adjacent side length can be found using:

{x}^{2}  +  {9}^{2}  =  {41}^{2}

This implies that:

{x}^{2}  =  {41}^{2}  -  {9}^{2}

{x}^{2}  =  1600

x =  \pm \sqrt{1600}

x =  \pm40

The cosine ratio is adjacent over hypotenuse.

=  \frac{ \pm40}{41}

Since we are in the second quadrant, the cosine ratio is negative;

=  -  \frac{40}{41}
