In a congressional district, 55% of the registered voters are Democrats. Which of
the following is closest to the probability of
getting less than 50% Democrats in a random
sample of size 100?
Is this an example of a sample proportion OR
a sample mean?

How many days was the temperature above 90 degrees?

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.)
