Harley-Davidson motorcycles make up 14% of all the motorcycles registered in the United States. You plan to interview an SRS of 520 motorcycle owners. (a) What is the approximate distribution of the proportion of your sample who own Harleys? Calculate the mean. Give your answer to 2 decimal places. mean: Calculate the standard deviation. Give your answer to 4 decimal places. standard deviation: (b) In 95% of all samples like this one, the proportion of the sample who own Harleys will fall between which two values? Give your answers to 3 decimal places. lower value: upper value:

Healthcare research agency reported that 47% of people who had coronary bypass surgery in 2008 were over the age of 65. Fifteen coronary bypass patients are sampled. What is the mean number of people over the age of 65 in a sample of 15 coronary bypass patients? Round the answer to two decimal places. What is the standard deviation of the number of people over the age of 65 in a sample of 15 coronary bypass patients? Round the answer to four decimal places.

The highway fuel economy of a 2016 Lexus RX 350 FWD 6-cylinder 3.5-L automatic 5-speed using premium fuel is a normally distributed random variable with a mean of μ = 21.00 mpg and a standard deviation of σ = 3.25 mpg. (a) What is the standard error of X-bar, the mean from a random sample of 16 fill-ups by one driver? (Round your answer to 4 decimal places.) Standard error of X-bar: 0.8125 (b) Within what interval would you expect the sample mean to fall, with 90 percent probability? (Round your answers to 4 decimal places.) The interval is from ____ to ____. Please use Excel function.
