When you sample the first individuals you can find, you call it a ; it's cheap and easy to do, but statistically not a very strong method.
a.
cluster
b.
stratified random sample
c.
convenience sample
d.
cluster sample
e.
simple random sample

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3
