The Aluminum Association reports that the average American uses
56.8 pounds of aluminum in a year. A random sample of 50 households
is monitored for one year to determine aluminum usage. If the
population standard deviation of annual usage is 12.3 pounds, what
is the probability that the sample mean will be each of the
following?
a. More than 58 pounds
b. More than 56 pounds
c. Between 55 and 58 pounds
d. Less than 53 pounds
e. Less than 47 pounds
(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)

A survey found that the American family generates an average of 17.2 pounds of glass garbage each year. Assume the standard deviation of the distribution is 2.5 pounds. Find the probability that the mean of a sample of 51 families will be between 16.7 and 17.7 pounds. Assume that the sample is taken from a large population and the correction factor can be ignored. Round your final answer to four decimal places and intermediate z-value calculations to two decimal places...

A survey found that the American family generates an average of 17.2 pounds of glass garbage each year. Assume the standard deviation of the distribution is 2.5 pounds. Find the probability that the mean of a sample of 43 families will be between 16.7 and 17.7 pounds. Assume that the sample is taken from a large population and the correction factor can be ignored. Round your final answer to four decimal places and intermediate -value calculations to two decimal places.

Part IV. Practical Applications Each American uses an average of 650 pounds of paper in a year. Assuming that the distribution normal with a standard deviation of 153.50 pounds find the probability that a randomly selected American uses: a. More than 800lbs of paper in a year. Answer: b. Less than 400lbs of paper in a year. Answer: C. Between 500 and 700 pounds of paper in a year. Answer:

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 47 who smoke. Step 1 of 2: Suppose a sample of 861 Americans over 47 is drawn. Of these people, 577 don't smoke. Using the data, estimate the proportion of Americans over 47 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 861 Americans...
