A clock is advertised as being 99% accurate. Would you buy it?
You can buy a car that is advertised for $15,000 on the following terms: (a) pay $15,000 and receive a $2,000 rebate from the manufacturer; or (b) pay $300 a month for 48 months. Which is the better deal if the interest rate is 6 percent per year and why?
A pendulum clock is accurate on earth, where the period of its pendulum is 1.00 s. (a) Find its period on the moon, where gravitational acceleration is 1.6 m/s2. (b) During a 2 h interval, what would be the elapsed time shown on the clock?

What would happen (other things being equal) to a confidence interval if you calculated a 99% confidence interval rather than a 95% confidence interval? Question 11 options: It will not change. It will be wider. It will be narrower.
Suppose you buy a new car whose advertised mileage is 26 miles per gallon (mpg). After driving your car for several months, you find that its mileage is 21.3 mpg. You telephone the manufacturer and learn that the standard deviation of gas mileages for all cars of the model you bought is 1.22 mpg. a. Find the z-score for the gas mileage of your car, assuming the advertised claim is correct. b. Does it appear that your car is getting...
37. A clock pendulum made of brass has a period of 0.500 s and is accurate at 20°C. If the clock is used in a climate where the temperature averages 30°C, what correction (approximately) is necessary at the end of 30 days to the time given by the clock? The coefficient of linear expansion for brass is α = 19 X 10-6/°C. Ans. 4.11 min 36 In a hurricane, the air (density 1.2 kg/m3) is blowing over the roof of...
You have a pendulum clock on the Moon, where g = 1.63 m/s2 . What rate does it run at, if that same clock keep accurate time on Earth? In other words, how long would it take (in hours) for the clock's hour hand to make one revolution on the Moon?
1. Amanda is running with a clock at 0.5c (c being the speed of light). To someone standing still (Bob) 10 minutes pass. How much time passes on Amanda's clock from Bob's point of view? The Bob is also holding a clock. If Amanda's clock says 15 minutes have passed, how much time passes on Bob's clock from Amanda's point of view? 2·
A recent newspaper circular advertised the following special on tires: “Buy three, get the fourth tire for free—limit one free tire per customer.” If a consumer has $360 to spend on tires and other goods and each tire usually sells for $40, how does this deal impact the consumer’s opportunity set?
What is a “design corner”? List the design corners that you would test for (a) clock speed; and (b) power consumption
