Consider trade in automobiles between the United States and Europe. The average European car costs €15,000. Suppose that the United States does not import any other goods and services from other countries. In March, the U.S. dollar-euro exchange rate is $1.16 per euro, and the United States imports 90,000 European cars at this exchange rate. Therefore, in March, the United States spends a total of on imported European cars. If the total value of U.S. exports is $0.52 billion, the...

please answer question 4 and 5
Birth Weights in America The National Center for Health Statistics (NCHS) keeps records of many health-related aspects of people, including the birth weights of all babies born in the United States The birth weight of a baby is related to its gestation period (the time between conception and birth). For a given gestation period, the birth weights can be approximated by a normal distribution. The means and standard deviations of the birth weights for...
