Concrete blocks are manufactured for construction. Assume the weights of the manufactured concrete blocks are normally distributed with a mean value of μ= 11.0 kg and a standard deviation of σ = 0.3 kg.
a. As an engineer, what rangeof weights do you expect to find in 99.3% of the population?
b. In a batch of 200 blocks, how many blocks do you expect to weigh less than 10.49 kg?
c. Draw a normal probability distribution labeling the mean and the horizontal axis. Shade in the percent less than 10.49 kg.
The next time you make a trip to a supermarket, ask the manager if you can measure the mass of at least 10 cereal boxes of your choice. Choose the same brand and the same size boxes. Tell the manager this is an assignment for a class. Report the average mass, variance, and standard deviation for the cereal boxes. Does the manufacturer’s information noted on the box fall within your measurement?
Repeat Problem using three other products, such as cans of soup, tuna, or peanuts.
