-
a-1. Develop a multiple regression equation with the amount of tips as the dependent variable and the amount of the bill and the number of diners as independent variables and complete the table. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
|
-
a-2. Write out the regression equation. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
|
-
a-3. How much does another diner add to the amount of the tips? (Round your answer to 2 decimal places.)
|
-
b-1. Complete the ANOVA table. (Leave no cells blank - be certain to enter "0" wherever required. Round "SS, MS" to 3 decimal places and "F" to 2 decimal places.)
|
-
c-1. Conduct an individual test on each of the variables. What is the decision rule at the 0.05 level of significance? (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
|
d. Use the equation developed in part (c) to determine the coefficient of determination. (Round your answer to 2 decimal places.)
The coefficient of determination is

Write a program that computes the tax and tip on a restaurant
bill for a patron with $44.50 meal charge. The tax should be 6.75%
of the meal cost. The tip should be 15% of the total after adding
tax. Display the meal cost, tax amount, tip amount, and total bill
on the screen. (I need this to be in OOP using C++)

1. At a certain restaurant in Ohio, the number of minutes that
diners spend at the table has a major impact on the profitability
of the restaurant. Suppose the average number of minutes that
diners spend at a table for dinner at the restaurant is 97 minutes
with a standard deviation of 18 minutes. Assume the number of
minutes diners spend at their table follows the normal probability
distribution. Complete parts a through d.
a. Calculate the probability that the...

Clint wrote a check to pay for his phone bill. The amount of the
bill was $50. He wrote out the words "Fifty dollars only" but he
also wrote "$60" in the area for numbers. As a result, the
check:
qualifies as a negotiable instrument, and the payee can collect
$60.
is disqualified as a negotiable instrument.
qualifies as a negotiable instrument, and the payee can collect
$50.
is disqualified as a negotiable instrument, unless Clint's
intent is ascertained.

The customer expectation when phoning a customer service line is
that the average amount of time from completion of dialing until
they hear the message indicating the time in queue is equal to 55.0
seconds (less than a minute was the response from customers
surveyed, so the standard was established at 10% less than a
minute).
You decide to randomly sample at 20 times from 11:30am until
9:30pm on 2 days to determine what the actual average

Results of a survey revealed that the distribution of the amount
of the monthly utility bill of a 3-bedroom house using gas or
electric energy had a mean of $97 and a standard deviation of
$12.
If the distribution of monthly bills can be considered
mound-shaped and symmetric, what percentage of homes will have a
monthly bill of more than $85 and less than $109?
If nothing is known about the shape of the distribution of
monthly bills, what percentage...
