To investigate the influence of distracted driving, 13volunteers were asked to participate in a studyHow would the correlation change if the stoppingdistances were recorded in meters, rather than feet?involving a driving simulator. The participants drove ata safe speed but were told to stop the car at a randommoment during the simulation.

Suppose two variables are negatively correlated. Does the response variable increase or decrease as the explanatory variable increases?
ab! ourses The accompanying technology output was obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of a sample of 40 people. Along with the paired sample data, the technology was also given a foot length of 13.6 cm to be used for predicting height. The technology found that there is a linear correlation between height and foot length. If someone has a foot length of 13.6 cm, what is the single value that is the best predicted height for that person?

Kris works for the MESA Air Pollution Study at UW, and studies the correlation be- tween air pollution and the disease atherosclerosis. Nationally, 40% of adults suffer from atherosclerosis. Kris suspects that the proportion of people with atherosclerosis in high- pollution areas is higher. In a random sample of 600 residents of high-pollution areas, he finds that 270 (45%) subjects have atherosclerosis. At the 1% level (α = .01), is this good evidence that people in high-pollution areas are more likely to have atherosclerosis? (a) Which of the following is the Ha ? (research claim or alternate) A. Ha : p ≥ 0.40 B. Ha : pb ≥ 0.40 C. Ha : p > 0.40 D. Ha : p > b 0.40 E. Ha : p > b 0.45 F. Ha : p > 0.45 G. Ha : pb ≥ 0.45 H. Ha : p ≥ 0.45 I.

The correlation between autonomy (how independent and in control of their own decisions someone feels) and sleep disturbance is -0.327. Explain this correlation in terms of size and direction (note: use the actual variables in your explanation).
This is two different samples though - younger students and older students. Paired samples T-test is for comparing the same group tested twice. Shouldn't the answer be correlation based on the us having two metric variables (age and number of complaints). We are testing whether, as age goes up, number of complaints also goes up, which you could see on a scatterplot using correlation?
Two items R and S belong to one test of numerical ability. Item R is passed by 50 and failed by 40 students in a group of 90 stu- dents. Item S is passed by 60 and failed by 30 students in the same sample. Find the correlation between R and S.
