Two Submit QuestionMicah is investigating how long his phone's battery lasts (in hours) for various brightness levels (on a scale of 0-100). His data is displayed in the table and graph below. Brightness Level (x) 17 17 51 53 73 86 88 99 Hours (y) 5.6 6.8 3.2 5.1 1.7 2.3 1.4 3.1 10 4 How's 10 20 30 40 50 60 70 80 90 100 11 Brightness Level a) Find the equation for the line of best fit. Keep at least 4 decimals for each parameter in the equation. Preview b) Interpret the slope in context. OMicah should expect -0.0531 brightness level per hour. OMicah should expect -0.0531 hours per brightness level. c) What does the equation predict for the number of hours the phone will last at a brightness level of 99? hoursAnnual high temperatures in a certain location have been tracked for several years. Let X represent the year and Y the high temperature. Based on the data shown below, calculate the correlation coefficient (to three decimal places) between X and Y. Use your calculator!
