  2. Raw Data

  3. Why this topic? • We chose this topic because music is a part of just about everyone's daily life. Music is a part of every culture with a wide variety of selection. • With the data that we gathered on cassettes, it shows us how music has changed in the ways we listen to it.

  4. Cassette • Confidence level: 95% • Alpha level: 0.025 • T-score: 2.228 • Z-score: 1.96 • Confidence Interval: 481.47<µ<1850.05 • We can be 95% confident that the single sales from 1994 to 2004 for cassettes is between 481.47 and 1850.05.

  5. Cassette • Confidence level: 98% • Alpha level: 0.02 • T-score: 2.764 • Z-score: 2.33 • Confidence Interval: 316.85 <µ< 2014.67 • We can be 98% confident that the single sales from 1994 to 2004 for cassettes is between 316.85 and 2014.67.

  6. cassette • Confidence level: 99% • Alpha level: 0.010 • T-score: 3.169 • Z-score: 2.58 • Confidence Interval: 192.46 <µ< 1090.06 • We can be 99% confident that the single sales from 1994 to 2004 for cassettes is between 192.46 and 1090.06.

  7. Best confidence interval • The best confidence interval is 95% because the range is not to broad or to narrow to gather an appropriate view of the population.

  8. Cassette Sales

  9. Real life Impact • As the confidence level gets higher, the wider the range of the confidence interval will be. This is because in the 99% confident level it is needed to cover all of the data ranges to cover all possibilities. • The drop of cassette’s was caused by the increased by sale of cd’s and the invention of the iPod.
