In this era of credit cards there is discussion on whether or
not coin use is declining. A professor has been collecting
data for years on the number of cents people carry in their
pockets or purses and maintains that the population mean
is 2.2 cents. She polls her current class and obtains the
following data: 1, 2, 3, 0, 0, 19, 43, 2, 7, 9, 0, 0, 1, 0, 5. Has
there been a change in the number of cents people
carry? (Report the appropriate statistics and state whether
you reject or accept the null hypothesis)
