One hundred students in a statistics course kept track of the time they spent on social media over the weekend. Each student recorded his or her time rounded to the nearest minute, so each observation is a whole number. The data are presented in the form of a frequency histogram. 26 25- 20 20- 16 15 14 12 10- 120 150 I80 210 30 Minutes on social media Each interval on the histogram contains the left endpoint, except for the last bar, which contains both the left and right endpoints. Give the lower and upper bound for the median number of minutes spent on social media over the weekend by the students enrolled in the class. The lower bound is the largest number that is less than or equal to the median, and the upper bound is the smallest number that is greater than or equal to the median. lower bound = 60 upper bound = 85 Kouanbasg

Evan 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.

Keep at least 4 decimals for each parameter in the equation.    b) Interpret the slope in context. Evan should expect -0.0604 hours per brightness level. Evan should expect -0.0604 brightness level per hour.   c) What does the equation predict for the number of hours the phone will last at a brightness level of 36?  hours
