- The following table is based on a random sample conducted of high school seniors and their parents by Jennings and Niemi, in which they explore the party identification of parents and their children.
Student Party Identification
|
Parent Party ID |
Democrat |
Independent |
Republican |
|
Democrat |
604 |
245 |
67 |
|
Independent |
130 |
235 |
76 |
|
Republican |
63 |
180 |
252 |
- What is the percentage of students who share the same party identification as their parents? (Show the computation.)
- What percentage of Democrat parents have Republican children?
- Based on these data, can we say if the relationship is causal? Explain your answer.
- Suppose you were exploring the hypothesis that there is a relationship between parents’ and children’s party identification. Would we be correct in inferring that such a relationship also exists in the population? Explain your answer. What is the probability that any relationship we found is due to pure chance?

11. High School Standardized Test Past experience indicates that
the time required for high school seniors to complete a
standardized test is a normal random variable with a mean of 35
minutes (normally distributed). If a random sample of 30 high
school seniors took an average of 33.5 minutes to complete this
test with a standard deviation of 4 minutes, test the hypothesis,
at the 0.05 level of significance, that u = 35 minutes against the
alternative that u <35...

Large Sample Proportion Problem. A survey was
conducted on high school marijuana use. Of the 2266 high school
students surveyed, 970 admitted to smoking marijuana at least
once. A study done 10 years earlier estimated that 45%
of the students had tried marijuana. We want to conduct a
hypothesis test to see if the true proportion of high school
students who tried marijuana is now less than 45%. Use
alpha = .01.
What is the conclusion for this test?
