A car accelerates from 0 to 40mph in 30 seconds. The speedometer reading at each 5 second interval during this time is given in the table below. Estimate how far the car travels during this 30 second period using the left point. Is this result an overestimate or an underestimate? sec vs mph 0 5 20- 10 T (seconds) 25 30 30 V (miles per hour) 0 6 14 15 23 36 40

A doctor works at a hospital estimate when to leave for work from his apartment; he decided to measure how long it takes him to go to the hospital every day. For one week, he records the time it gets him to drive from his apartment to the hospital, including searching for parking and reaching to his office. The data are as follows: M Eighty-one      Min T Fifty-four         Min W Seventy           Min R Fifty-two          Min F Forty-three      Min 1- Will you recognize these times as a sample or a population? and way 2- Obtain the mean and the standard deviation for the time it requires him to go to his office at the hospital. 3- Lets say his roommate, who is working with him at the same hospital and same office, takes the train to the hospital. She records the time it takes her to get to the office during the exact week and was that her mean was Sixty-two minutes, and the standard deviation was Five. Based on these measurements, it is convenient to drive or ride the…
