MATH 225N Week 8 Assignment Predictions Using Linear Regression The table shows data collected on the relationship between the time spent studying per day and the time spent reading per day. The line of best fit for the data is yˆ=0.16x+36.2. Assume the line of best fit is significant and there is a strong linear relationship between the variables.  According to the line of best fit, what would be the predicted number of minutes spent reading for someone who spent 67 minutes studying? Rou...

MATH 225N Week 8 Assignment: Correlation and Causation True or False: The more samples taken in a scientific study, the longer the amount of time it will take to complete the research on the samples. Although there are other factors that affect study time, such as experience and equipment, increasing the number of samples will cause an increase in research time. Correct! You nailed it. Suppose that a large controlled experiment tests whether caffeine improves reaction times. A very large numb...
