QUESTION 1 TESTING WEATHER STATIONS FOR MARS A company has signed a contract to develop a "weather station" for use on Mars. It will continually measure temperature and wind speed. It must work in extreme cold and in the presence of fine dust, for one Martian year. The company wants to test its design, by building several prototypes, and subjecting the prototypes in a lab to conditions similar to Mars. The company claims the probability is 80% that a weather station will perform satisfactorily. The company builds and tests ten prototypes. These prototypes are built and tested independently. If the company's claim is correct that the probability of a weather station performing satisfactorily is 80%, what is the probability at least eight of the prototypes will perform satisfactorily? What sampling distribution should we use to compute this probability? a. binomial b. normal c. approximately normal (CLT) d.t e. chi-square
