LSRL and Computer Output 3. An emergency service wishes to see whether a relationship exists between the high outside temperature on a given day and the number of emergency calls it receives. They examine data from 10 randomly selected days last year. The data is as follows: Temperature 74 82 88 No. of Calls 4 8 10 67 8 93 99 11 14 101 78 85 90 13 6 8 10 a) Find the least squares regression line. State the equation below and interpret the slope and y- intercept b) Find and interpret the value of r. c) Create a residual plot on your calculator. What does this plot tell you about a linear model for this data? How do you know? d) Find and interpret the residual for 93. e) What point represents the largest residual? What does that residual mean?
