In the course, go to Unit 9 -> Instructor Graded Project -> StatCrunch to access the MM207 Student Data Set. When the page loads you will need to click on Data Set on the left side of the page. You do not need a StatCrunch ID or a password to access the data set; simply click the on Data Set to load the data file.

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

2. Using the MM207 Student Data Set:
a) Select a continuous variable that you suspect would not follow a normal distribution. Age would not follow a normal distribution.
b) Create a graph for the variable you have selected to show its distribution. [pic]
c) Explain why these data might not be normally distributed. They would not normally be distributed because people of all ages go to school. Look at the mean and how the values are not close to the mean.
a) Select a second continuous variable that you believe would approximate a normal distribution. Height is my continuous variable that I chose.
d) Create a graph to show its distribution. [pic]
e) Explain why these data might be normally distributed. People come in all different heights, however you see a closer grouping around the mean, which suggests that these values are closer to normal distribution.
3. Jonathan is a 42 year old male student and Mary is a 37 year old female student thinking about taking this class. Based on their relative position, which student would be farther away from the average age of their gender group based on this sample of MM207 students? Jonathan.
Summary statistics for Q2 How old are you?:
Group by: Gender
|Gender |n |Mean |
|Female |138 |0.7976879 |
|Male |35 |0.20231214 |
5. Using the sample of MM207 students:
a) What is the probability of randomly selecting a person who is conservative and then selecting from that group someone who is a nursing major?
For Conservative it is: 41 Conservative/175 total or 41/175 or 0.243 or 23%
