Textbook Question

Chapter 4.1, Problem 52E

Imports from Vietnam The value of U.S. imports from Vietnam (in billions of dollars) can be approximated by the function

f ( x ) = 2.48 e .179 x ,

where x = 9 corresponds to the year 2009. (Data from: The Wall Street Journal.)

Find the value of U.S. imports in 2014?

If the trend continues, what is the first full year when imports exceed $60 billion in value?

(b) In various places in this module, data on the silver content of coins minted in the reign of the twelfth-century Byzantine king Manuel I Comnenus have been considered. The full dataset is in the Minitab file coins.mwx. The dataset includes, among others, the values of the silver content of nine coins from the first coinage (variable Coin1) and seven from the fourth coinage (variable Coin4) which was produced a number of years later. (For the purposes of this question, you can ignore the variables Coin2 and Coin3.) In particular, in Activity 8 and Exercise 2 of Computer Book B, it was argued that the silver contents in both the first and the fourth coinages can be assumed to be normally distributed. The question of interest is whether there were differences in the silver content of coins minted early and late in Manuel’s reign. You are about to investigate this question using a two-sample t-interval. (i) Using Minitab, find either the sample standard deviations of the two variables…
