Question: Technology on campus. Every 5 years the Conference Board of the Mathematical Sciences surveys college math departments. In 2000 the board reported that 51% of all undergraduates taking Calculus I were in classes that used graphing calculators and 31% were in classes that used computer assignments. Suppose that 16% used both calculators and computers.
a) What percent used neither kind of technology?
b) What percent used calculators but not computers?
c) What percent of the calculator users had computer assignments?
d) Based on this survey, do calculator and computer use appear to be independent events? Explain.
Draw a picture illustrating each of the following distributions, showing the t-values marking the specified areas and the proportion of the t-distribution that falls in that area.
Recognize independent variable and dependent variable for this experiment. Think in your head what influences what? Or, what causes what? Cause is independent variable.
