Telephone interviews of 1, 502 adults 18 years of age or older found that only 69% could identify the current vice-president.
is the value a parameter or a statistic?

a. the value is a parameter because the 1, 502 adults 18 years of age or older are a sample.
b. the value is a parameter because the 1, 502 adults 18 years of age or older are a population.
c. the value is a statistic because the 1, 502 adults 18 years of age or older are a population.
d. the value is a statistic because the 1, 502 adults 18 years of age or older are a sample.

D

Step-by-step explanation:

The population consists of all characteristics of interest and sample is portion or a subset of population. Here, 1502 adults 18 years or older are select ted from a population of all adults 18 years or older, so, 1502 adults are the sample. The measurement taken from sample is termed as statistic. The given value 69% is computed from a sample and thus it is a sample statistic.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
