Vivian surveyed 3 of her classmates to find out the amount of time they spend on the cell phone on the weekend. The hours spent were 2. 7hr, 5.1 hr, and 4.2 hr, with the mean of 4 hours.Calculate the standard deviation using the following formula for variance:%3Dn-1Note: All the letters highlighted in blue need to be filled in with your answers. All values must be rounded to the nearest tenth (eg. 3.0, not 3 nor 3.02)Racetime X,-(X-)inhoursForForX2ForX3Write the values in each of the blanks above (note-for i, use the same order as values given in the problem).What is the value of the numerator 2X- H)*?
