Using JAVA
The
Jumpin'
Jive
coffee shop charges $2 for a cup of coffee and offers the add-ins
shown in Table 6-2.
Design the logic for an application that allows a user to enter
ordered add-ins continuously until a
sentinel value is entered. After each item, display its price or
the message Sorry, we do not carry
//that as output. After
all items have been entered, display the total price for the
order.

A manufacturer of computers claims its newest model has a mean
battery life of 10 hours, although normally distributed variations
in computer production will cause some units to have more or less
battery life. A consumer advocacy group is concerned the true mean
is less and is constructing a hypothesis test at the 95%
significance level to evaluate the claim. In their testing for
battery life, a sample of 25 randomly selected units gave a sample
mean of ̄x25 =...
