The daily exchange rates for the five-year period 2003 to 2008 between currency A and currency B are well modeled by a normal distribution with mean 1.466 in currency A (to currency B) and standard deviation 0.041 in currency A. Given this model, and using the 68-95-99.7 rule to approximate the probabilities rather than using technology to find the values more precisely, complete parts (a) through (d). a) What is the probability that on a randomly selected day during this period, a unit of currency B was worth less than 1.466 units of currency A? The probability is nothing%. (Type an integer or a decimal.) b) What is the probability that on a randomly selected day during this period, a unit of currency B was worth more than 1.548 units of currency A? The probability is nothing%. (Type an integer or a decimal.) c) What is the probability that on a randomly selected day during this period, a unit of currency B was worth less than 1.343 units of currency A? The probability is nothing%. (Type an integer or a decimal.) d) Which would be more unusual, a day on which a unit of currency B was worth less than 1.388 units of currency A or more than 1.533 units of currency A? More than 1.533 is more unusual. Less than 1.388 is more unusual.

The mean incubation time for a type of fertilized egg kept at a certain temperature is 17 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day . Complete parts (a) through (e) below. Part (a) Draw a normal model that describes egg incubation times of these fertilized eggs. Part (b) Find and interpret the probability that a randomly selected fertilized egg hatches in less than days. The probability that a...
In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally distributed, with a mean of 4.7 and a standard deviation of 2.4. Answer parts (a)dash(d) below a) Find the probability that a randomly selected study participant's response was less than 44. The probability that a randomly selected study participant's response...
