Problem 4

MTV Some students do homework with the TV on. (Anyone come to mind?) Some researchers want to see if people can work as effectively with as without distraction. The researchers will time some volunteers to see how long it takes them to complete some relatively easy crossword puzzles. During some of the trials, the room will be quiet; during other trials in the same room, a TV will be on, tuned to MTV. a) Design an experiment that will require a two-sample t procedure to analyze the results. b) Design an experiment that will require a matched-pairs t procedure to analyze the results. c) Which experiment would you consider the stronger design? Why?

T wo quantitative variables: Linear Regression Purpose: How to use one variable to predict the other when there is a linear trend. Linear regression: process of fitting a line to a set of data, the line of best fit is called the regression line. Equation for a line: y=a+bx, where a is the y-intercept and b represents the slope of the line.  Finding the regression line means finding values for the slope and intercept of the line that best describes the linear trend of the data. Example: If data pairs are (x,y) with as the explanatory variable and y as the response, the regression line is given by y(hat)=a+bx. Regression line is often called a prediction equation because we can use it to make predictions in certain situations, for example in a tipp
