Chapter 5.4, Problem 26E
Loans Find the monthly payment and estimate the remaining balance (to the nearest dollar). Assume interest is on the unpaid balance. The interest rates are from national averages from www.bankrate.com in October 2016. (See Examples 4 and 5.)
Three-year used car loan for $15,875 at 2.89%; remaining balance after 1 year

(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.
