6. Continue with problem 5. 4. n- (a) Interpret a Type I crror in terms of the problem. (b) Interprct a Type II crror in terms of the problem. (c) Calculate a 99% confidence interval for the true differ- ence in average systolic blood pressure. (d) Interpret the interval from (c) in terms of the problem, being as specific as you can. (e) What is the largest difference between the two groups you would expect with 99% confidence? Be sure to specify the direction of the difference. 7. Three high schools participated in a study to evaluate the effectiveness of a new computer-based mathematics cur- riculum. In each school, four 24-student sections of fresh- man algebra were available for the study. The two types of instruction (standard, computer-based) were randonly assigned to the four sections in each of the three schools. At the end of the term, a standardized mathematics test. was given to the 24 students in eachh section. (a) Is this an experimental, observation, or mixed study?

Answer:
a) Is this an experimental, observation or mixed study?
This is an observational study
b) What is the primary variable of interest (the response variable)?
The response variable is score or grade in standardized mathematics test
c) What are the explanatory variables? Identify all levels of the explanatory variables (factor levels) if appropriate.:
Factor (treatment): The variable that is changed and results are observed
Explantory variables are: Standard Instructions and Computer-based Instructions
Level: A value assigned to change the factor.
d) Identify all combinations of the explanatory variables.
