specificity (
Activity 9
Part I: (Adapted from Exercise 4.11)
In a study done in England, Voss and Mulligan (2000) collected data on
height (short or not) and whether or not the student had ever been bullied in
school for 209 secondary school students. The following is

Log into ANGEL and go to the Lab Activities folder for today. Then, open the dataset Spring
Survey Results in Minitab. This data was collected during four previous sections of Stat 200.

Relationships between Two Quantitative Variables
Part I: Whenever we have two quantitative measurements on the same individual, it may be
interesting to know if there is a relationship between the two variables. A simple scatterplot of

Part I: Making an assumption about the physical world (the dice).
Many games involve rolling two 6-sided dice (eg: Monopoly and casino
craps). In this activity, we will find the probabilities for these outcomes,
specifically the sum of the dice

Part I: Normal Probabilities
Suppose that X = amount that a randomly selected student at PSU spent on textbooks this
semester is a normal random variable with mean = $400 and standard deviation = $85.
It follows that Z = (X 400) / 85 is a stan
Activity 14:
Confidence Intervals for One Proportion
Part I: The data for this part are in the Spring 2006 Survey Results data set found on ANGEL.
This represents a sample from the population of all Penn State students. We plan to use this sample
data to

Confidence Intervals for Two Proportions
Part I: Open the worksheet Spring 2006 Survey Results data. Recall from Activity 14 our
comparison between PSU students from big cities and PSU students from small towns. We defined
