- What does a G01 tell a machine to perform?arrow_forwardYou want to know if the type of music one listens to while running impacts their speed. You recruit 50 participants. These participants listen to classical music while running two laps on a track. You time how long it takes each person to run those two laps. A week later, the same participants run two laps on the track while listening to country music. You time how long it takes each person to run those two laps. All else held constant, which of the following would increase power? O Use alpha .01. O Reduce participants to 40. O Use a directional hypothesis.

- The gestation period of rabbits is about 29 to 35 days. Therefore the population of a form can increase dramatically in a short period of time. The table gives a population of a form we're tea is the time in months and then is the rabbit population.arrow_forwardThe constant is used in mathematics, physics, and other related fields such as engineering ertensively. In this exercise, you are going to compute an approximation of the constant T. Gambler Jack is no mathematician. His friends laugh at him and make a bet that Jack does not know the number x, not even the first three most significant digits. Jack is going to lose the bet but his girlfriend, Jane, is an accountant and she is going to help. She suggested Jack the following idea. r. 2r Figure 3: A circle with radius r inside a square with sides of length 2r. 1. Use a cireular dartboard of radius r inside a square of length 2r as shown in Figure 3. 2. Throw n mumber of darts randomly onto the dartboard. 3. Count the number m of darts that falls inside the circle. 4. The ratio of m over n is approximately a quarter of a circle. If you are still lost, the conversation above can be distilled into the following equation for computing the probability p of the dart landing inside the cirele:…arrow_forwardA roasted turkey is taken from an oven when its temperature has reached 185 Fahrenheit and is placed on a table in a room where the temperature is 75 Fahrenheit.

Andrea walks down the escalator as it is moving down, and walks down 50 steps by the time she reaches the bottom. Marty runs down the escalator as it is moving down, and runs down 90 steps by the time he reaches the bottom. Marty does this in the same time that Andrea takes to walk down 10 steps. How many steps are visible when the escalator is not moving? Note: Andrea walks down the steps at a constant speed. Also, Marty runs down the steps at a constant speed as well.arrow_forwardActivity 3: Your car's gas tank holds 18.6 gallons and is one quarter full. Your car gets 16 miles/gal. You see a sign saying, "Next gas 73 miles." Your often-wrong brother, who is driving, is sure you'll make it without running out of gas. You're not so sure and do some quick figuring 18.6 gal 1 tank 4 quarter tank 1 gal 1 tank 16 miles 74.4 miles quarter tank "Ah! I knew I was right," declares your brother on glancing at your calculator, "your calculations prove it!" Is this a good time to be assertive and demand that he turn around to get gas, or do you conclude that your brother is right for once?arrow_forward
