Summer temperatures (in Fahrenheit degrees) in two adjacent cities in 9 consecutive days are observed and given below. You are curious about whether temperatures in City A can be used as an independent variable (x) to estimate temperatures in City B (y). 75 55 73 72 83 95 97 99 67 y| 79 73 78 36 47 86 99 99 69 (Click the button to copy or download the data.) (a) Use Excel or another software to estimate the linear regression line y =+ x. (Round b, and b, to one and three decimal places, respectively, including any zeros.) (b) Based on part (a), if the temperature in City A in a certain day is 85 F, we can estimate the temperature in City B as y = (Round to one decimal place, including any zeros.)
