Chapter 1, Problem 13CQ
Suppose that a friend states the hypothesis that the color of socks that he wears on a given day, brown or black, will determine whether the stock market will go up or down. He can cite several instances in which this hypothesis has been apparently verified. How would you go about evaluating this hypothesis?

Solve the following problem. Round off the final answer to three decimal places.
A popular web site state that a 200 pound person will burn 450 calories/hour bicycling
(moderate effort) and 650 calories/hour rock climbing (ascending). A 150 pound person
decides to start a training routine in which she will bicycle for 45 minutes, 3 times a week and
rock climb for 1.50 hours every weekend. How many calories will she have burned after 8 weeks
of training (assuming she consumes at the same rate)?
A typical bathroom sink faucet releases about two gallons of water every minute.
a) If it takes you 2.5 minutes to brush your teeth and you leave the water run for the entire time, how much water would be used?
b) If you only run the water for 30 seconds, how much water would be used?
Estimate how many molecules of air are in each 2.5-L breath you inhale that were also in the last breath Galileo took. [Hint: Assume the atmosphere is about 10 km high and of constant density.]
Express your answer using two significant figures.
N=?? (I got 27, but I was also wrong).

- I believe the solution to the problem at this url is incorrect and that the problem requires integration. I asked this problem once before and got a very different answer (64 gallons versus 11 gallons as provided in this answer). The previous solution was much more involved but I had a hard time following the solution so I asked the question again. I would like this problem solved by a different expert please. https://www.bartleby.com/questions-and-answers/5.-oil-flows-into-a-tank-according-to-the-rate-ft11-and-at-the-same-time-empties-out-at-the-rate-et-/cdf8b9dc-0b1c-4bfc-bb53-ad200f80692barrow_forwardThe following table shows the number of students in three different degree programs and whether they are undergraduate students or graduate students: Degree Program Undergraduate GraduateTotal Business 150 50200 Engineering 150 25175 Arts & Sciences 100 25125 Total 400 100 500 What is the probability that a randomly selected student is an undergraduate?arrow_forwardOne mole of Gold (Au) atom has a mass of 197 g.
