Question
The table shows the results of a poll of 1,000 people. Respondents were asked to agree or disagree with the statement “I rely too much on my phone.” If a respondent who was selected at random disagrees with the statement, which of the following is closest to the probability that the respondent selected is at least 45 years old?
- 0.37
- 0.45
- 0.49
- 0.55
The correct answer is: 0.55
The total people disagreeing are 548
The total people disagreeing aged at least 45 are 201 + 102 = 303
The probability =

For a sample of 13 red alder trees, an arborist measured each tree’s diameter, in centimeters (cm), at a height of 1.4 meters. The arborist then counted the number of growth rings at this height. Each point in the scatterplot represents the diameter and number of rings for each tree. A line of best fit for these data is also shown.
A red alder tree will be selected at random from the sample. What is the probability that the selected tree will have a measured diameter that is greater that is greater than 30 cm?
