In a study comparing response rates between treated and non-treated subjects, 30% of subjects are observed to have both responded and been treated. If we also know that a randomization ratio of 1:1 was used (e. g. 1 out of every 2 subjects were treated), then we can calculate that the probability of response among treated subjects is. a.

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.)
