The daily exchange rates for thefive-year period 2003 to 2008 between currency A and currency B are well modeled by a normal distribution with mean
The daily exchange rates for thefive-year period 2003 to 2008 between currency A and currency B are well modeled by a normal distribution with mean 1.755 in currency A(to currencyB) and standard deviation 0.014 in currency A. Given thismodel, and using the68-95-99.7 rule to approximate the probabilities rather than using technology to find the values moreprecisely, complete parts(a) through(d).
c) What is the probability that on a randomly selected day during thisperiod, a unit of currency B was worth c) What is the probability that on a randomly selected day during thisperiod, a unit of currency B was worth more than 1.797 units of currency A?
