...MM207 Final Project 1. Using the MM207 Student Data Set: a) What is the correlation between student cumulative GPA and the number of hours spent on school work each week? Be sure to include the computations or StatCrunch output to support your answer. My answer : 0.27817234 (from StatCrunch): Correlation between Q10 What is your cumulative Grade Point Average at Kaplan University? and Q11 How many hours do you spend on school work each week? is: 0.27817234 b) Is the correlation what you expected? My answer: No. I expected the correlation to be much higher because the more hours you study should equate to a much higher GPA – in theory that is. c) Does the number of hours spent on school work have a causal relationship with the GPA? My answer: Yes. I was going to say no (because of the low correlation above), until I did a scatter plot. This shows that MM207 Final Project there definitely is a casual relationship between study time and GPA. yuck. There are 2 points on the right that most likely could be excluded. d) What would be the predicted GPA for a student who spends 16 hours per week on school work? Be sure to include the computations or StatCrunch output to support your prediction. My answer: 3.6 from StatCrunch Group by: Q11 How many hours do you spend on school work each week?

...way influenced by the researcher. They were solely asked to answer the question and their answers were not manipulated. 3. In the following scenario what is the statistic and the parameter it would estimate. A recent study of 460 drivers age 70 and over by the National Highway Traffic Safety Administration reported that 75% of those drivers had uncorrected vision problems. * The reported statistic would be 75% of the 460 drivers age 70 and over. Which would be a total of 345 drivers age 70 or older that had uncorrected vision problems. * The parameter would be the total population of drivers age 70 and over the have uncorrected vision problems. 4. What type of sampling procedure was used to collect the data in the MM207 Student Data Set? - I think that this would be a convenience sample because it is using the population of college students in the sampling. This is a total of 175 Kaplan...

...scenario what is the statistic and the parameter it would estimate. A recent study of 460 drivers age 70 and over by the National Highway Traffic Safety Administration reported that 75% of those drivers had uncorrected vision problems. Answer: The report of the ‘traffic safety administration’ reported that 75% (345 people) was the reported statistic from the 460 drivers of 70 or older drivers. I feel the assumed parameter would be the population of drivers that had uncorrected vision that were 70 years old or older. 4. What type of sampling procedure was used to collect the data in the MM207 Student Data Set? Answer: The sampling procedure used, believe was the ‘Conveyance’ sampling because this was a population which was readily available.
