A soft drink vending machine dispenses cans of drinks at the
JKUAT cafeteria. The machine waits for students and/or staff to
insert coins. All soft drinks cost KShs. 50 and the machine can
only accept Ten, Twenty and Forty shilling coins. A customer must
insert a total of fifty shillings for the machine to dispense
drinks.

Diet versus Regular Soft Drinks (take assumptions or
random readings)
Cans of soft drinks are so common that many people have done
much of this exploration without realizing it. You, too, have
probably cooled soft drink cans in ice water for a picnic. Here is
your opportunity to see if you can make some generalizations about
their behavior in water.
Materials
• 1 12-fl oz (355 mL) aluminum can
of diet soft drink, unopened
• 1 12-fl oz (355 mL) aluminum...

A soft drink manufacturer wishes to know how many soft drinks
teenagers drink each week. They want to construct a 90% confidence
interval with an error of no more than 0.07. A consultant has
informed them that a previous study found the mean to be 5.6 soft
drinks per week and found the standard deviation to be 1.4. What is
the minimum sample size required to create the specified confidence
interval? Round your answer up to the next integer.

A machine that fills beverage cans is supposed to put 12 ounces
of beverage in each can. Following are the amounts measured in a
simple random sample of eight cans. 11.96 12.10 12.04 12.13 11.98
12.05 11.91 12.03
Perform a hypothesis test to determine whether the mean volume
differs from 12 ounces. Use a 0.05 level of significance.
Also construct a 99% confidence interval for the data.

A machine that fills beverage cans is supposed to put 12 ounces
of beverage in each can. Following are the amounts measured in a
simple random sample of eight cans: 12.15 12.17 12.20 11.88 12.16
12.04 12.05 12.11 Perform a hypothesis test to determine whether
the mean volume is greater than 12 ounces. Use the α=0.05 level of
significance and the critical value method. Compute the value of
the test statistic. Round the answer to three decimal places.
