  1. What’s your opinion on the support teachers give you? Rate 1-10. Yesenia Espinoza Period#1 2012-2013

  2. California Standards: •8.0 Student organized and describe distribution of data by using of different methods, including frequency table, histogram, standard line and bar graphs, stem-and-leaf displays, scatter plots, and box of whisker plots. •17.0 Students determine confidence interval for a simple random sample from a normal distribution of data and determine the sample size required for a desired margin of error. •18.0 Student determine the P-value for a statistic for a simple random sample from a normal distribution

  3. Hypothesis: • I believe that the average commute support from teachers at Century is rate 6.

  4. Data Collection: • I used the census sampling technique. In every class I asked all the students and in lunch I asked my friends and got a rating. • The bias was that I missed the other classes and all my friends in 2nd lunch. • I collected data by using the census sampling method. In every class I asked all my classmates so I can get everyone’s rating.

  5. Data: • Length in support(rating 1 being the lowest and 10 being the highest) • 5, 4, 4, 6, 6, 6, 6, 5, 7, 6, 4, 2, 0, 0, 10, 1, 7, 7, 5, 6, 6, 4, 5, 2, 3, 3, 8, 4, 1, 4, 5, 5, 5, 8, 8, 10, 10, 10, 3, 7, 7, 5, 8, 6, 7, 7, 10, 9, 9,10, 6, 6, 5, 4, 8, 8, 8, 9, 9, 9, 10, 10, 7, 7, 7, 5, 9, 5, 8, 8, 8, 7, 5, 5, 9, 5, 6, 4, 7, 8, 9, 6, 9, 6, 6, 6, 6, 7, 8, 9, 9, 9, 6, 6, 5, 4, 9, 8, 8, 8,

  6. Statistics: • From my survey student’s sample rating mean is 6.42 with sample standard deviation 2.31.

  7. Confidence interval: • 95% confidence interval • Z-interval • (5.9672,6.8728) • I am 95% confident the mean ratings from all students are between 5.96~6.87.

  8. Hypothesis Testing: • Hypothesis • Test Statistics T-test Conclusion:At 5% level of significance, we failed to reject . There is enough evidence to support our claim.

  9. Error Analysis: • My sample mean is rating of 6.42, and the 95% confidence level for the students asked mean is between ratings of 5.96 to 6.87. • My sample error was that I missed the other classes and all my friends in 2nd lunch.I might need to take more samples due to my limit of people to ask in first lunch, students fail to take interest in rating their teachers support.

  10. Conclusion: • I hypothesized that the rating average of students is 6. In my survey of 100 students, I found the sample mean rating of 6.42 with a standard deviation rating of 2.31. I conclude that the rating mean for all the students is between 5.96 to 6.87 with 95% confident. I test my initial hypothesis with 5% level of significance, and confirm my hypothesis is correct.
