Textbook Question
Chapter 2, Problem 51SE
Musicians Survey: StatCrunch Graph The accompanying graph is a special histogram with additional information; it was made using StatCrunch. People who studied music as children were asked how many hours a day they practiced when they were teenagers, and whether they still play now that they are adults. To understand the graph, look at the third bar (spanning 1.0 to 1.5); it shows that there were seven people (the light red part of the bar) who practiced between 1.0 and 1.5 hours and did not still play as adults, and there were two people (the light blue part of the bar) who practiced 1.0 to 1.5 hours and still play as adults. Comment on what the graph shows. What other types of graphs could be used for this data set?

(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…
