Determine whether the random variable is discrete or continuous.
a. the height of a randomly selected giraffeheight of a randomly selected giraffe.
b. the number of light bulbs that burn out in the next week in a room with 20 bulbsnumber of light bulbs that burn out in the next week in a room with 20 bulbs.
c. the number of hits to a website in a daynumber of hits to a website in a day.
d. the distance a baseball travels in the air after being hitdistance a baseball travels in the air after being hit.
e. the amount of snowfallamount of snowfall.

Respuesta :

A) continuous
B) discrete
C) discrete
D) continuous
E) continuous

A)Since the values between data points would still be applicable to the situation (heights can be fractional numbers) it is connected or continuous.
B) You cannot have a fraction of a light bulb that burns out; therefore the values between data points have no real life application, and the data would be disconnected (discrete).
C) You cannot have a fraction of a hit to a website; therefore the values between data points have no real life application, and the data would be disconnected (discrete).
D) Distance would have applicable values between data points; we can have 1 foot, 0.5 feet, 0.25 feet, etc.  This means the data would be connected (continuous).
E) Snowfall would have applicable values between data points; we can have 1 inch, 0.5 inches, 0.25 inches, etc.  This means the data would be connected (continuous).
