Jack has surveyed their 25 classmates about the number of cars in their household and received the following data: 5 5 3 0 2 3 3 2 6 4 4 5 4 6 2 2 4 0 4 1 1 1 0 Construct a frequency and relative frequency distribution table: (Round the relative frequencies to 2 decimal places) Number of cars M 53 0 1 2 3 4 5 6 Total: Frequency 3 3 4 4 5 4 2 Relative Frequency % % % % % % % %

Back up your data: In a survey backed up their computer's hard drive. The following frequency distribution presents the results. mmissioned by an electronics company, U.S. computer users wereasked how often they Response More than once per month Frequency 844 Once every 1-3 months 521 Once every 4-6 months 229 Once every 7-11 months Once per year or less Never

In a student survey, forty-one part-time students were asked how many courses they were taking this term. The (incomplete) results are shown below: Please round your answer to 4 decimal places for the Relative Frequency if possible. # of Courses Frequency Relative Frequency Cumulative Frequency 1 15 0.3659 15 2 12 0.2927   ? 3   ?    ? 41  What percent of students take exactly one courses          ? %
