1What happens to the curve when the standard deviation is increased? What does that do to the area under the curve? 2What happens to the curve when the standard deviation is decreased? What does that do to the area under the curve?

The answer is below

Explanation:

Z score is a score used in mathematics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

The area under the curve is dependent on the z score. The higher the z score, the higher the area under curve and the lower the z score, the lower the area under curve.

a) The area under curve (z score) is inversely proportional to the standard deviation. If the standard deviation is increased, the z score decreases thereby reducing the area under the curve.

b) If the standard deviation is decreased, the z score increases thereby increasing the area under the curve.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
