A random sample of 36 cups of soda dispensed from the old soda machine in the lobby had a mean amount of soda od 7 ounces. Assume that the population standard deviation is 1 ounce. a. Find the best point estimate of the amount of soda dispensed. b. Construct and interpret a 95% confidence interval for the true population mean amount of soda dispensed from the old soda machine in the lobby.
Solutions
Expert Solution
We are 95% confident that the true population mean amount of soda dispensed from the old soda machine in the lobby is from 6.67 ounces to 7.33 ounces.

Write a program that determines the change to be dispensed from
a vending machine. An item in the machine can cost between 25 cents
and 1 dollar, in 5-cents increments (25, 30, 35, . . . 90, 95, or
100), and the machine accepts only a single dollar bill to pay for
the item. (Explain with algorithms if you can please!)

A random sample of 36 individuals were selected from the batch
of products to estimate a feature of interest. Suppose that the
sample mean is 125 and the standard deviation for this batch is
assumed to be 24.
a) construct a 95% confidence interval for the mean value for
this feature of the batch.
b) if we want to make the sampling error +/- 7, how many more
individuals should be selected to achieve a confidence level
95%?
c) based...

In a random sample of 43 teenage males it was found that the
amount of soda they consumed daily had a mean of 33.42 ounces with
a standard deviation of 9.98 ounces. At the 1% level of
significance can it be shown that teenage males consume a mean of
less than 36 ounces of soda per day?
(a) State and test appropriate hypotheses. State
conclusions.
(b) Find the p-value of the test in (a).
The old machine filled 12 soda cans with an average of 11.9 oz of soda with a standard deviation of 0.3 ounces.
The old machine filled 12 soda cans with an average of 11.9 oz of soda with a standard deviation of 0.3 ounces. The new machine still fills them (11 cans) with an average of 12.1 ounces, with a standard deviation of 0.3 oz. Is the new machine filling with significantly more than the old machine? (α=.05)
