The flow rate y (m3/min) in a device used for air-quality measurement depends on the pressure drop x (in. of water) across the device's filter. suppose that for x values between 5 and 20, the two variables are related according to the simple linear regression model with true regression line y = −0.13 + 0.095x. what is the expected change in flow rate associated with a 1 in. increase in pressure drop?

For a school newspaper article, cienna conducted a survey to find out students’ favorite subjects. she polled all the students in mrs. lopez’s advanced dance class. why is her data likely to be skewed? honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented. cienna should have interviewed all the students in the school to get more accurate data. honors dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented. cienna should have interviewed only every other student in the class to avoid having too many people.
