Someone wants to build a large wooden sculpture in the shape of a soccer ball outdoors (this was actually built in germany for the world cup). a) being outdoors, how does the higher expected moisture content affect the strength of the wood members? b) this "ball" needs to be designed for dead loads (its own weight) and wind loads. in terms of load duration, what do you need to consider when you look at strength properties for those two kinds of loads?

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends > a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
